Sansa Clip+: add RDS support
Based on a patch by Amaury Pouly which was based on a patch from Ryan
Hitchman.
I mainly moved the code for polling into the tuner driver so it can be
reused by other targets. I added the CONFIG parameter for the polling
frequency (in ticks) to save energy. Also, I did some minor cleanups.
