[Intel-gfx] [PATCH v2 2/9] drm/i915/display/psr: Do full fetch when handling multi-planar formats

[José Roberto de Souza]

From: Gwan-gyeong Mun <gwan-gyeong.mun at intel.com>

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.
