drm/connector: Allow drivers to pass list of supported colorspaces

Drivers might not support all colorspaces defined in
dp_colorspaces and hdmi_colorspaces. This results in
undefined behavior when userspace is setting an
unsupported colorspace.

Allow drivers to pass the list of supported colorspaces
when creating the colorspace property.

v2:
 - Use 0 to indicate support for all colorspaces (Jani)
 - Print drm_dbg_kms message when drivers pass 0
   to signal that drivers should specify supported
   colorspaecs explicity (Jani)

v3:
 - Move changes to create a common colorspace_names array
   to separate patch

v6:
- Avoid magic when passing 0 for supported_colorspaces;
  be explicit in treating it as "all DP/HDMI"
