[media] friio-fe: convert set_fontend to use DVBv5 parameters
Instead of using dvb_frontend_parameters struct, that were designed for a subset of the supported standards, use the DVBv5 cache information. Also, fill the supported delivery systems at dvb_frontend_ops struct. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
