drm/i915: Improve DP downstream HPD handling
DP dongles may signal downstream HPD via short HPD pulses. Setting the
sink to DPMS off apparently kills the downstream HPD (at least on my
DP->VGA dongle), so skip the DPMS off for such dongles when we turn
off the port.
v2: Deal with DDI as well by moving the check into
intel_dp_sink_dpms() (Dhinakaran)
