drm/i915: Program SHPD_FILTER_CNT on CNP+
The bspec tells us 'Program SHPD_FILTER_CNT with the "500 microseconds
adjusted" value before enabling hotplug detection' on CNP+. We haven't
been touching this register at all thus far, but we should probably
follow the bspec's guidance.
The register also exists on LPT and SPT, but there isn't any specific
guidance I can find on how we should be programming it there so let's
leave it be for now.
