Fix problems with volume of recorded material by converting 14-bit samples to
16-bit. Remove duplicate samples from recorded data and support proper
samplerate since ADC runs 1/2 the codec clock. Support monitoring mono on both
output channels by feeding data manually to I2SOUT under the right conditions.
DMA is no longer used for recording since frames must be processed as described
above but it does allow full-duplex audio.
Miscellaneous change includes a proper constant (HW_SAMPR_DEFAULT) to reset the
hardware samplerate when recording is closed. PP5024 and AS3525 have different
default recording rates (22kHz and 44kHz respectively) but both have half-speed
ADC.

Reserve 1MB of DRAM for loading rockbox and use the rest as BSS
Write sdram setup in assembler and move it to a separate file, together
with MMU init code

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

We can write to DBOP_DOUT in 8 bits mode : bits 7..0 are mapped to the
LCD, not bits 15..12 and 3..0 like on Clipv1

Flyspray: FS#10371
Authors: Fred Bauer and myself
Only enabled on e200v2 and Fuze (crashes on clipv1)

Still disabled on all targets:
- Fuze and e200v2 see spurious interrupts with no source defined
- Clip/m200v4 deadlock instantly when starting recording (perhaps due to low memory size)
Having the code in SVN will make working on this feature easier
Also add keymaps for Fuze, and correct Frequency section of recording
options : the 22.05kHz limitation of e200v1 and c200v1 doesn't apply to
Sansa AMS (different I2S hardware, unrelated to as3514)

Unaligned (to 4byte boundary) and odd (where the amount of data is not an integer multiple of 32bit) are still supported. Even those still have a speedup of >2.

Note : SH has TIMER_FREQ defined to CPU_FREQ, so any code wanting it must include #config.h before #cpu.h

- cache IRAM and DRAM
- map IRAM just next to DRAM to remove the need for -mlong-calls and reduce binsize
- tweak delays in Fuze button code
- tweak delays in Clip button code (down button sometimes doesn't respond anyway : an alternate driver is being worked on)
