In order to use a common VSC SDP Colorimetry calculating code on PSR, it uses a new psr vsc sdp compute routine. Because PSR routine has its own scenario and timings of writing a VSC SDP, the current PSR routine needs to have its own intel_dp_vsc_sdp structure member variable on struct i915_psr.
In order to include "struct intel_dp_vsc_sdp" to "struct i915_psr", it moves definition of "struct intel_dp_vsc_sdp" to i915_drv.h . And in order to calculate colorimetry information, intel_psr_update() function and intel_psr_enable() function extend a drm_connector_state argument.
There are no changes to PSR mechanism.
