drm/i915: Enable hpd logic only for ports that are present
Let's enable the hardware hpd logic only for the ports we
can actually use.
In theory this may save some miniscule amounts of power,
and more importantly it eliminates a lot if platform specific
codepaths since the generic thing can now deal with any
combination of ports being present on each SKU.
v2: Deal with DG1
v3: Deal with DG1 some more
