drm/i915/icl: Handle expanded PLANE_CTL_FORMAT field
ICL+ adds changes the PLANE_CTL_FORMAT field from [27:24] to [27:23],
however, all existing PLANE_CTL_FORMAT_* definitions still map to the
correct values. Add an ICL_PLANE_CTL_FORMAT_MASK definition, and use
that for masking for the conversion to fourcc.
v2: No changes
v3: Change new definition name, drop comment (Rodrigo)
