    drm/i915/psr: Print Panel Replay status instead of frame lock status
    
    [ Upstream commit 51ee1f29a9aceb8a52037ba4759d44c70e966fe5 ]
    
    Currently Panel Replay status printout is printing frame lock status. It
    should print Panel Replay status instead. Panel Replay status register
    field follows PSR status register field. Use existing PSR code for that.
