[PATCH 5/6] drm/i915/mtl+: Use PHY type to identify TypeC ports in PLL ID lookup

[Imre Deak <imre.deak@intel.com>]

Use the PHY type to identify TypeC ports in the PLL ID lookup function.
This ensures that port B takes the TypeC path when an upcoming change
sets its PHY type to TypeC on PTL+ platforms with an eDP panel connected
to a TypeC PHY.
