055071195c si4700 tuner: lower stereo switchover range, so it switches to stereo for weaker signals. Should fix FS#11405.

adc472bec5 FM tuner region code cleanup - FS #11492 by me. 
This removes the tuner-specific region structs and makes each driver use the common one (which is now extended with a deemphasis field)

e236b95746 Si4700 tuner: It doesn't like to do i2c while powered off and hangs the bus. Make 'pause' simply be 'mute', allowing tuning during user mute as well as nicer-sounding unmute.

2e99b3d931 Gigabeat S: Allow recording from FM. Give FM the same volume range as playback. NOTE: This bumps the si4700 output volume to -0dB so other players with that may need a minor adjustment.

1fea6f6b22 Make si4700 tuner driver more sane with bit and field defines and entirely hide strange i2c interface from code with write/set/clear/masked functionality. On Gigabeat S use by-the-book busmode selection and GPIO lines. Implement some primitive station detection, debug registers in screen, and misc. changes to tie things together.

51322432a0 Update si4700 FM driver: 
* implement 16-bit register cache and use #defines for registers
* add support for enabling the internal oscillator (needed for AMS sansas)

65f61d6cce FS#9609 FM radio support for the Gigabeat S, seeking/scanning is not yet 
implemented but manual tuning works nicely. Thanks to Rafaël Carré,
Bertrik Sikken and Robert Menes for suggestions and debugging help.
