Make the icl function generic so it is based on phy type and can be
applied to tgl as well.
I checked if this could not apply to EHL as well, but unfortunately
there the HPD and DDC/GMBUS pins for DDI C are mapped to TypeC Port 1
even though it doesn't have TC phy.
v2: don't add a separate function for TGL, but rather reuse the ICL one
(suggested by Rodrigo)
