drm/msm: clear colorimetry block info for HDMI
SDE connector stores the information related to the HDMI
colorimetry data block. This connector information is
retained till the connector is destroyed which does not
happen across hotplug.
Clear the HDMI colorimetry block related data fields when
the bridge is disabled so that across a hotplug stale
information is not retained.
