drm/i915/gen11: Handle watermarks correctly for separate Y/UV planes, v2.
Skylake style watermarks program the UV parameters into wm->uv_wm,
and have a separate DDB allocation for UV blocks into the same plane.
Gen11 watermarks have a separate plane for Y and UV, with separate
mechanisms. The simplest way to make it work is to keep the current
way of programming watermarks and calculate the Y and UV plane
watermarks from the master plane.
Changes since v1:
- Constify crtc_state where possible.
- Make separate paths for planar formats in skl_build_pipe_wm() (Matt)
- Make separate paths for calculating total data rate. (Matt)
- Make sure UV watermarks are unused on gen11+ by adding a WARN. (Matt)
