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.

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

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
