drm/i915: Fix watermark calculations for gen12+ MC CCS modifier
commit 484b2b9281000274ef7c5cb0a9ebc5da6f5c281c upstream.
Take the gen12+ MC CCS modifier into account when calculating the
watermarks. Othwerwise we'll calculate the watermarks thinking this
Y-tiled modifier is linear.
The rc_surface part is actually a nop since that is not used
for any glk+ platform.
v2: Split RC CCS vs. MC CCS to separate patches
Cc: stable@vger.kernel.org
Fixes: 2dfbf9d2873a ("drm/i915/tgl: Gen-12 display can decompress surfaces compressed by the media engine")
