drm: Rename HDMI colorspace property creation function
As between HDMI and DP have different colorspaces, in order to distinguish colorspace of DP and HDMI, it renames drm_mode_create_colorspace_property() function to drm_mode_create_hdmi_colorspace_property() function for HDMI connector. In order to apply changed drm api, i915 driver has channged. It addresses review comments from Ville. - Split hunk into renaming and adding of code.
