From: Eric Yang <Eric.Yang2@xxxxxxx> [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.
