drm/i915/psr: Do not override PSR2 sink support

Browse Source 
Sink can support our PSR2 requirements but userspace can request
a resolution that PSR2 hardware do not support, in this case it
was overwritten the PSR2 sink support.
Adding another flag here, this way if requested resolution changed
to a value that PSR2 hardware can handle, PSR2 can be enabled.
