[media] siano: split get_frontend into per-std functions
Browse files Browse the repository at this point in the history 
Instead of handling both DVB-T and ISDB-T at the same get_frontend
function, break it intow one function per-delivery system.
That makes the code clearer as we start to add support for DVBv5
statistics, and for ISDB-T get frontend stuff.
