Subject: drm/i915/display/psr: Do full fetch when handling multi-planar
formats

Git-commit: 1f61f0655b95d5b89589390e6f83c4a61d9b1e8d
Patch-mainline: v5.16-rc1

We are still missing the PSR2 selective fetch handling of multi-planar
formats but until proper handle is added we can workaround it by
doing full frames fetch when state has such formats.
