Patches 1/4,2/4,3/4 are minor fixes.

DPSUB requires input live video format to be configured.
Patch 4/4: The DP Subsystem requires the input live video format to be
configured. In this patch we are assuming that the CRTC's bus format is fixed
and comes from the device tree. This is a proposed solution, as there are no api
to query CRTC output bus format.

Is this a good approach to go with?
