YP-CP3: record the FM radio at +12 dB by default

Browse source 
The radio is heard through the codec's input PGA at +12 dB, but on
the recording screen the gain started at 0 dB, so a recording was
much quieter than what was heard just before. Start the line gain,
which the radio uses, at +12 dB.

Defining the defaults also makes the line gain a saved setting on
this target; before, it went back to 0 dB at every boot.

Tested on a YP-CP3: switching from the FM screen to the recording
screen with FM as the source keeps the same loudness.
