[media] drivers/media/radio/radio-timb.c: use devm_ functions

Browse source 
The various devm_ functions allocate memory that is released when a driver
detaches.  This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.
