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.

FCLK is unused because we use fastbus clocking: CPU clock = PCLK
Base PCLK off PLLA and use the lowest frqeuency for FCLK (24MHz source,
maximum divider)
Save a bit of power, adjust Clipv1/e200v2/Fuzev1 current usage accordingly
Note: the power saving (in mA) is a bit less on e200v2/Fuzev1 than on Clipv1

AMS*: define CURRENT_MAX_CHG to give more correct estimation of recharge time
The amount of current each target draws from the charger is defined in
powermgmt-target.h

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

- 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

Use smaller recording buffer and watermarks on these models with 2MB of ram
Rearrange watermark calculation expressions so we can use fractional
numbers of seconds but still with integer results
Only enable spinup time adjustement for ATA targets
Flash targets (sansas and ondiofm) should still work fine, but they were
not tested
