drm/i915/tgl: Add DC3CO mask to allowed_dc_mask and gen9_dc_mask
Enable dc3co state in enable_dc module param and add dc3co
enable mask to allowed_dc_mask and gen9_dc_mask.
v1: Adding enable_dc=3,4 options to enable DC3CO with DC5 and DC6
independently. [Animesh]
v2: Using a switch statement for cleaner code. [Animesh]
