media: bttv: radio use v4l2_fh instead of bttv_fh

Browse source

Use a v4l2_fh when opening a radio device instead of a bttv_fh and manage
it with v4l2_fh_open() and v4l2_fh_release() and v4l2_ctrl_poll(). This
eliminates bttv_fh from the radio in preparation for vb2 conversion which
stops using separate bttv file handles altogether.
