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.
