    drm/i915/dp: Disable the AUX DPCD probe quirk if it's not required
    
    Reading DPCD registers has side-effects and some of these can cause a
    problem for instance during link training. Based on this it's better to
    avoid the probing quirk done before each DPCD register read, limiting
    this to the monitor which requires it. The only known problematic
    monitor is an external SST sink, so keep the quirk disabled always for
    eDP and MST sinks. Reenable the quirk after a hotplug event and after
    resuming from a power state without hotplug support, until the
    subsequent EDID based detection.
