HF-VSDB/SCDB has bits to advertise support for 16, 12 and 10 bpc.
If none of the bits are set, the minimum bpc supported with DSC is 8.
This patch corrects the min bpc supported to be 8, instead of 0.

timings,
I have used the check for clock >= 2376 MHz (or 1188 MHz with 420
format), instead of using individual VICs.
While at it, fix a bug while parsing the compressed bpc supported
