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. Change-Id: I95a62e7e1e42c62dbf47ecb27a3b312a42be62aa
