drm/amd/display: fix zstate allow interface to PMFW

Browse source

[Why]
psr_feature_enabled flag is dynamically updated, and sometimes when
zstate allow status is determined the flag has not been set to true yet
even on PSR enabled config, lid off/on is such a case, which will result
in zstate disabled even though PSR is supported.

[How]
Check the supported PSR version and the PSR disable status instead.
