[media] xc5000: Add support for 7MHz bandwidth for DVB-C/DVB-T
While xc5000 supports 7MHz bandwidth, the driver were lacking the code
implementing this feature, causing tuning issues with VHF chanels
used in Countries like Italy.
After this patch:
>>> tune to: 177500000:INVERSION_AUTO:BANDWIDTH_7_MHZ:FEC_2_3:FEC_AUTO:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_32:HIERARCHY_NONE
