drm/i915/ptl+: Add TypeC HPD pin selection for port B
Handle the TypeC PHY on port B case while mapping the port to an HPD
pin. This prepares for an upcoming change that will set port B's PHY
type to TypeC on PTL+ platforms with an eDP panel connected to a TypeC
PHY.
Keep the existing port >= PORT_TC1 case and its HPD pin mapping for
DG2, where PORT_TC1 has a non-TypeC PHY.
