drm/i915/dp: Track pm_qos per connector
Since multiple connectors may run intel_dp_aux_xfer conncurrently, a single global pm_qos does not suffice. (One connector may disable the dma-latency boost prematurely while the second is still depending on it.) Instead of a single global pm_qos, track the pm_qos request for each intel_dp. v2: Move the pm_qos setup/teardown to intel_dp_aux_init/fini Fixes: 9ee32fea ("drm/i915: irq-drive the dp aux communication") Signed-off-by:Chris Wilson <chris@chris-wilson.co.uk> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Imre Deak <imre.deak@intel.com> Reviewed-by:
