[media] Change frontend allocation strategy for NetUP Universal DVB cards
Old behaviour:
frontend0 - DVB-S/S2
frontend1 - DVB-T/T2
frontend2 - DVB-C
frontend3 - ISDB-T
New behaviour (DVBv5 API compliant):
frontend0 - DVB-S/S2
frontend1 - DVB-T/T2/C/ISDB-T
DTV standard should be selected by DTV_DELIVERY_SYSTEM call.
And DVB-C default bandwidth now 8MHz
