Sansa AMS recording support (Microphone and FM)

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)
