drm/amd/display: Add timing pixel encoding for mst mode validation

Browse source

[Why] Mode pbn is not calculated correctly because timing pixel encoding is
not checked within convert_dc_color_depth_into_bpc.

[How] Get mode kbps from dc_bandwidth_in_kbps_from_timing, then calculate
pbn by kbps_to_peak_pbn.
