FiiO M3K: audio recording

Recording works now, although I'm sure there will be a few
things that need fine-tuning. A major issue is that writing
to the SD card creates noticable interference, which happens
on the original firmware too but seems worse under Rockbox.

(Since Rockbox waits until RAM fills up before writing data,
the interference will only be heard on >50 MiB recordings.)
