drm/xe/display: Create a dummy version for vga decode

Browse Source 
This introduces an exclusive version of vga decode for xe.
Rest of the display changes will be re-used from i915.

Currently it adds just a dummy implementation. VGA decode
needs to be handled correctly in i915, proper implementation
will be adopted once the i915 changes are finalized and merged
in upstream.

v2: Addressed Arun's review comments
