drm/connector: Use common colorspace_names array

Browse Source 
We an use bitfields to track the support ones for HDMI
and DP. This allows us to print colorspaces in a consistent
manner without needing to know whether we're dealing with
DP or HDMI.

v4:
- Rename _MAX to _COUNT and leave comment to indicate
  it's not a valid value
- Fix misplaced function doc

v6:
- Drop magic in drm_mode_create_colorspace_property for
  dealing with "0" supported_colorspaces. Expect the caller
  to always provide a non-zero supported_colorspaces.
- Improve error checking and logging
