drm: Rename HDMI colorspace property creation function

Browse Source 
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.
