drm/i915/wm: Nuke wm->uv_wm[]

Browse source

We currently keep around the full watermarks for the UV plane
on pre-icl, even though the hardware doesn't need most of this
information. The only thing we need to keep is the min_ddb_alloc
for the UV plane. Move that into the main wm->wm[].min_ddb_alloc_uv
alongside the other min_ddb_alloc (used for Y/RGB).

This makes our state tracking match the hardware more closely,
and avoids having to justify everwhere why uv_wm[] is being
ignored.
