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)
