    drm/i915/dp_mst: Work around Thunderbolt sink disconnect after SINK_COUNT_ESI read
    
    Due to a problem in the iTBT DP-in adapter's firmware the sink on a TBT
    link may get disconnected inadvertently if the SINK_COUNT_ESI and the
    DP_LINK_SERVICE_IRQ_VECTOR_ESI0 registers are read in a single AUX
    transaction. Work around the issue by reading these registers in
    separate transactions.
    
    The issue affects MTL+ platforms and will be fixed in the DP-in adapter
    firmware, however releasing that firmware fix may take some time and is
    not guaranteed to be available for all systems. Based on this apply the
    workaround on affected platforms.
    
    See HSD #13013007775.
