drm/i915: Fix watermark calculations for DG2 CCS+CC modifier
Take the DG2 CCS+CC modifier into account when calculating the
watermarks. Othwerwise we'll calculate the watermarks thinking this
tile-4 modifier is linear.
The rc_surface part is actually a nop since that is not used
for any glk+ platform.
