drm/i915/psr: program vsc header for psr2
Function hsw_psr_setup handles vsc header setup for psr1 and
skl_psr_setup_vsc handles vsc header setup for psr2.
Setup VSC header in function skl_psr_setup_vsc for psr2 support,
as per edp 1.4 spec, table 6-11:VSC SDP HEADER Extension for psr2
operation.
v2: (Jani)
- Initialize variables to 0
- intel_dp_get_y_cord_status and intel_dp_get_y_cord_status made static
- Correct indentation for continuation lines
- Change DP_PSR_Y_COORDINATE to DP_PSR2_SU_Y_COORDINATE_REQUIRED
- Change DPRX_FEATURE_ENUMERATION_LIST to DP_DPRX_*
- Change VSC_SDP_EXT_FOR_COLORIMETRY_SUPPORTED to DP_VSC_*
