drm/amd/display: Set default bits per channel
[Why]
Bump into calcReducedBlankingTiming because of mode query failed.
In this function,
timing.displayColorDepth == DISPLAY_COLOR_DEPTH_UNDEFINED.
Then req_bw == 0 because of bits_per_channel == 0.
So decide edp link settings, use default RBRx1 for special timing.
[How]
Set default bits_per_channel is 8.
