Subject: drm/i915/display/psr2: Mark as updated all planes that intersect with
 pipe_clip
MIME-Version: 1.0

Git-commit: 5cc92edb6ee8ac6f6d6d4fd8e7ecd00407a2489a
Patch-mainline: v5.15-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

Without this planes that were added by intel_psr2_sel_fetch_update()
that intersect with pipe damaged area will not
have skl_program_plane() and intel_psr2_program_plane_sel_fetch()
called, causing panel to not be properly updated.
