drm/amd/display: Add expanded HBlank field to dc_crtc_timing

Browse source

[Why]
For DP HBlank expansion/reduction, the HBlank parameters of the original
EDID timing needs to be notified to the sink in order for the timing to
be reduced back to the original HBlank size.

[How]
Add parameter in dc_crtc_timing to track the increased HBlank.
