[Intel-gfx] [PATCH 5/7] drm/i915/display/psr: Do full fetch when handling biplanar formats

["José Roberto de Souza" <jose.souza@intel.com>]

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

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