drm/i915: Implement UHBR bandwidth check

Browse source

According to spec, we should check if output_bpp * pixel_rate is less
than DDI clock * 72, if UHBR is used.

v2: - s/pipe_config/crtc_state/ (Jani Nikula)
    - Merged previous patch into that one, to remove empty function(Jani Nikula)

v3: - Make that constraint check to be DSC-related only
    - Limit this to only DISPLAY_VER <= 13

v4: - Move constraint check to the top(Vinod Govindapillai)
