[Intel-gfx] [PATCH 1/4] drm/i915: Don't check uv_wm in skl_plane_wm_equals()

From: Ville Syrjälä The hardware never sees the uv_wm values (apart from uv_wm.min_ddb_alloc affecting the ddb allocation). Thus there is no point in comparing uv_wm to determine if we need to reprogram the watermark registers. So let's check only the rgb/y watermark in skl_plane_wm_equals().
