drm/i915/psr: Disable psr1 if setup_time > vblank

Browse source

Issue is seen when PSR enabled with setup frames and when try to disable
PSR at SRDONACK State (0x1). PSR FSM is stuck at SRDONACK(0x1) for more
than 5 seconds. Issue not seen with Setup frames disabled. Currently
disable psr1 if setuptime > vblank to workaround the above issue.
