drm/i915/dp: Attach colorspace property
It attaches the colorspace connector property to a DisplayPort connector.
Based on colorspace change, modeset will be triggered to switch to a new
colorspace.
And in order to distinguish colorspace bwtween DP and HDMI connector, it
adds a handling of drm_mode_create_dp_colorspace_property() to
intel_attach_colorspace_property().
Based on colorspace property value create a VSC SDP packet with appropriate
colorspace. This would help to enable wider color gamut like BT2020 on a
sink device.
v9: Addressed review comments from Ville
- Add a handling of drm_mode_create_dp_colorspace_property() to
intel_attach_colorspace_property(). This hunk moved from the previous
commit.
