drm/i915/display: Only keep PSR enabled if there is active planes
PSR always had a requirement to only be enabled if there is active
planes but not following that never caused any issues.
But that changes in Alderlake-P, leaving PSR enabled without
active planes causes transcoder/port underruns.
Similar behavior was fixed during the pipe disable sequence by
commit 84030adb9e27 ("drm/i915/display: Disable audio, DRRS and PSR before planes").
intel_dp_compute_psr_vsc_sdp() had to move from
intel_psr_enable_locked() to intel_psr_compute_config() because we
need to be able to disable/enable PSR from atomic states without
connector and encoder state.
