affects all hiby targets, fiiom3k, and ibasso dx50/dx90
As well as deduplicating a small pile of code, this also implements
hysteresis so we're not doing a sysfs read/lookup multiple times
back-to-back every time the power management tick fires.

Previously these were placed in DRAM, which is overwritten by RoLo
when it loads a new image, but RoLo must call commit_discard_idcache()
after loading the image.

The filesystem API often passes in unaligned receive buffers, and some
code (eg BMP reader) processes data in-place, leading to data loss when
we dropped the cache.
(And document exactly what we're doing, so we don't go through this again
at $future_date)

In fixing the original bug I tried to optimize discard_dcache_range()
to minimize writeback and inadvertently introduced a second bug, which
typically ends in a TLB refill panic.
It occurs only if the range fits within one cache line, and when both
the start and end of the range are not aligned to a cache line. This
causes ptr to be incremented and end to be decremented, so ptr > end,
and the loop can't terminate.

- The range-based cache operations on MIPS were broken and only worked
properly when BOTH the address and size were multiples of the cache
line size. If this was not the case, the last cache line of the range
would not be touched!
Fix is to align start/end pointers to cache lines before iterating.
- To my knowledge all MIPS processors have a cache, so I enabled
HAVE_CPU_CACHE_ALIGN by default. This also allows mmu-mips.c to use
the CACHEALIGN_UP/DOWN macros.
- Make jz4760/system-target.h define its cache line size properly.

ATA DMA was enabled for all PP502x targets in d118f47 after previously reported instabilities were thought to have been fixed. The iPod 4G target remains unstable when UDMA 2 is enabled. File system corruption will eventually occur even using stock hardware in normal usage, according to both my own experience and that of several other forum users. UDMA 1 appears to be stable.

Basically no longer treat SCROLL_FWD/BACK as "button" events, instead
relying on the scrollwheel hooks to handle things properly.

v3: Add in config option
v4: Bugfixes
v5: Force a redraw upon exiting
v6: keypress-in-chargeonly mode enables mass storage (and vice versa)
v7: Fix bootloader builds
v8: Update manual, and have bootloader respect keypresses
v9: Change default to mass storage (ie no change in behavior)
todo:
* test-build dx50/dx90
* Switch from yes/no to proper menu?

This was introduced in e13c600133 back
when the author was trying to optimize the LCD code with DMA. For
whatever reason this broke the bootloader for the last 10 years or so
and no one could figure out why. This is now fixed.
However the bootloader is still currently broken in HEAD due to recent
changes to the LCD code. A fix for that is not yet known.

Some mSATA adapters seem to have trouble working with Rockbox using our
normal PIO timings; the timing value we use is probably out of spec and
is different to the OF. Switch to using the OF's timings according to
which PIO mode we select. This may not completely resolve problems with
these adapters but allows Rockbox to boot and play audio.

Also audiohw driver to specific device name, rewrite alsa controls code to
cache more data, thus making the code easier and use less stack. Avoid using
short/long in pcm alsa code since it's the wrong size on 64-bit (simulator
for example)

Nothing in the core has used it for some time. It's exported to the
plugin API but the last plugins to use it were switched to the mixer API
back in 2011.
This allows us to get rid of pcm_play_dma_pause() from all audio drivers

Basically we're overflowing IRAM by 48 bytes. Shrink the stack
by 48 bytes to compensate.
Fixing this properly will require careful decisions about what
(code and/or data) to eject from IRAM.

I'm currently running up against the limitations of the lcd_draw functions
I want these functions to be able to be used on any size buffer not
just buffers with a stride matching the underlying device
[DONE] allow the framebuffer to be decoupled from the device framebuffer
[DONE need examples] allow for some simple blit like transformations
[DONE] remove the device framebuffer from the plugin api
[DONE}ditto remote framebuffer
[DONE] remove _viewport_get_framebuffer you can call struct *vp = lcd_set_viewport(NULL) and vp->buffer->fb_ptr
while remote lcds may compile (and work in the sim) its not been tested on targets
[FIXED] backdrops need work to be screen agnostic
[FIXED] screen statusbar is not being combined into the main viewport correctly yet
[FIXED] screen elements are displayed incorrectly after switch to void*
[FIXED] core didn't restore proper viewport on splash etc.
[NEEDS TESTING] remote lcd garbled data
[FIXED] osd lib garbled screen on bmp_part
[FIXED] grey_set_vp needs to return old viewport like lcd_set_viewport
[FIXED] Viewport update now handles viewports with differing buffers/strides by copying to the main buffer
[FIXED] splash on top of WPS leaves old framebuffer data (doesn't redraw)
[UPDATE] refined this a bit more to have clear_viewport set the clean bit and have skin_render do its own screen clear
scrolling viewports no longer trigger wps refresh
also fixed a bug where guisyncyesno was displaying and then disappearing
[ADDED!] New LCD macros that allow you to create properly size frame buffers in you desired size without wasting bytes
(LCD_ and LCD_REMOTE_)
LCD_STRIDE(w, h) same as STRIDE_MAIN
LCD_FBSTRIDE(w, h) returns target specific stride for a buffer W x H
LCD_NBELEMS(w, h) returns the number of fb_data sized elemenst needed for a buffer W x H
LCD_NATIVE_STRIDE(s) conversion between rockbox native vertical and lcd native stride (2bitH)
test_viewports.c has an example of usage
[FIXED!!] 2bit targets don't respect non-native strides
[FIXED] Few define snags

* Get rid of nonblock mode; we never write if buffers aren't sufficient
* Move driver init into pcm_open() instead of pcm_init()
* Much better underrun handling
* Better error handling in some situations
* Add in recording functionality
* Use smaller audio buffers to avoid glitching
* Don't start audio buffer with silence
* Allow device name to be overridden by target

* Set hw/swparams prior to actual playback start, not at init
