[media] vez1820: convert set_fontend to use DVBv5 parameters
Browse files Browse the repository at this point in the history
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.
