drm/i915: For HPD connected port use hpd_pin instead of port.

Browse source 
Let's try to simplify this mapping to hpd_pin -> bit
instead using port.
So for CNL with port F where we have this port using
hdp_pin and bits of other ports we don't need to duplicated
the mapping.

But for now this is only a re-org with no functional change
expected.

v2: Add missing lines and nuke @port reference from code
    documentation. (Ville)
