    drm/i915/dp: Fix the enabling/disabling of audio SDP splitting
    
    Adjust the enabling/disabling steps of the DP audio SDP splitting
    according to a recent Bspec update. This moves the enabling to the audio
    codec enable sequence after the transcoder is enabled and disables SDP
    splitting explicitly during the audio disable sequence.
    
    Bspec requires waiting for a vblank event after the transcoder is
    enabled and before SDP splitting is enabled. There is no need for an
    explicit wait for this, since after the transcoder is enabled this
    vblank event is guaranteed to have happened via a flip done wait (see
    intel_atomic_commit_tail() -> drm_atomic_helper_wait_for_flip_done()).
    
    The bspec update is for LNL+ only, but the HW team clarified that this
    has been always the intended sequence on all platforms and bspec will be
    updated everywhere accordingly.
    
    The way SDP splitting was originally enabled matched the version of
    bspec at that time. Adding here the Fixes: line still, since this
    change fixes a FIFO underrun on PTL during output enabling when DSC is
    enabled.
