We can't pop into pc on ARMv4t when using thumb: the T bit won't be
modified if we are returning to a thumb function
Code running on ARMv4t should use the new ldrpc / ldmpc macros instead
of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc}
No modification on pure ARM builds and ARMv5+
Note: USE_THUMB is currently never defined, no targets can currently be
built with -mthumb, see FS#6734

This adds proper full speed charging support for iPod 4G, Color, Mini 1G, Mini 2G, Nano 1G, and Video. Nano 2G already has support, so now all ipods charge (except 1G-3G whose hardware doesn't support USB charging).
USB charging defaults to on, but will only charge at full speed from a USB host. To charge from an AC charger, you need to set the USB charging mode to "force". It may be possible to detect AC chargers in a future version, at least on some models.

Enable support for the "force" mode of USB charging. This should work on Gigabeat S and Nano2g (and any other future target which has a RB usb stack and supports charging) - if a host connection is not detected within 10 seconds of USB insertion, assume that the connected device is an AC charger and charge anyway, if the user has specified "force" as the mode.

1) "Charge during USB connection" option is now tristate: off/on/force. Currently "force" behaves just like "on", but in future it will allow charging even when it was not possible to positively identify a charger.
2) The H300 code has been adjusted to use the new system but there should be no functional differences, it already had the USB charging option and its USB/charging support is hardware controlled.
3) The Gigabeat S code has been adjusted to use the new system: the player now has the USB charging option, which wasn't previously available. The player will only charge at full speed when allowed to do so by a working USB host, so USB AC adapters won't work very well; however, they didn't work before either, so this is not a change in functionality.
4) The iPod Nano 2G code has been adjusted to use the new system: it already had the USB charging option. Using a USB AC adapter won't charge at full speed any more (it did before) - the old implementation was equivalent to the not-yet-implemented "force" option in the new system.
No other target should be affected. Support for the "force" mode and support for at least some other iPod models will come in a future commit :)

tick_start, fmradio_i2c_init, pcm_init, pcm_postinit, pcm_play_dma_init
Also add some as3525 target specific functions
Make as3525v2 use this attribute

Declare VIC registers holding function pointers as volatile pointers to
function pointers and access them directly without casting
UIRQ() is an IRQ handler too, even if it doesn't return

- enhance registers description in header file with respect to the as3543
registers: point which one are present or not in the as3543, which bits
change (i didn't detail all registers)
- cache less registers, only up to the ones which are written to
multiple times
- use ascodec_readbytes() to cache all needed registers in a row
- separate the as3543 bits from as3514/as3515 in audiohw_preinit()
- comment out unused audiohw_set_lineout_vol
- some cosmetics

Bring Clipv1 & m200v4 plugin buffer down to this limit
zxbox, chessbox and rockboy build on the clip
rockboy doesn't build on m200v4 due to not enough buttons to make a keymap
Some gameboy roms won't run on Clipv1: tetris does but not pokemon for example

build it on fuzev2 and clipv2 too, it should be the same controller
as3525v1 file is only build for CONFIG_USBOTG == USBOTG_AS3525, no need
to check for it in the .c file

- only enable overlays for targets with very small plugin buffer (<=
0x10000 bytes, i.e. archos)
- change the condition for rockboy to reflect exactly why it can be
built or not
- Some plugins need a large plugin buffer, only enable them if the
buffer is big enough (sizes measured on Clipv1)
- disable MIDI if we have 2MB (or less), we won't be able to load the
instruments in the audio buffer
- remove unusable lua overlay loader
- sokoban code is bigger on clipv1 than on SH, assume it code is 20kB on
anything but SH so it builds with buffer smaller than 192kB
- reduce the Clipv1 plugin buffer size from 288kB to 96kb, disabling
zxbox, chessbox, and fft
zxbox and chessbox have overlays which run on archos, we just need to
enable them on other targets. We'll also be able to run rockboy.
fft won't run as it needs a large plugin buffer for greylib

To be sure that there is no mistake in this code, it is run *after*
the known to work HOME & LEFT buttons checks, unlike other Sansas

- Enable end of charge monitoring once, it doesn't need to be disabled
- Acknowledge the first (wrong) end of charge interrupt on charger enable
(this had been broken in r25299)
- Centralize reads to ENRD* registers and cache the results when needed
- on PP it is not needed because reads are atomic, we only check for
end of charge when the charging, and for charger presence when
discharging
as3525v2 (using as3543) specifics
- I got the datasheet today from AMS, thanks to them for being so fast
and not require me to sign tons of papers!
- USB detection now works on as3525v2 using the as3543. Clip+ won't
reboot to OF yet, it needs mkamsboot support first (usbstack disabled)
- Charging should work, the CHARGER register is at a different place, it
is an extended PMU register -> use ascodec_read/write_charger() to
access it
- real interrupts are not used yet for ENRD, we get thousands of
interrupts per second, apparently only limited by the i2c clock.
