Semantics of port#0 differ between ICL and TGL:
ICL port#0 -> never used for HDAudio
ICL port#1 -> should be mapped to first pin (0x04)
TGL port#0 -> typically not used, but HW has the support,
so should be mapped to first pin (0x04)
TGL port#1 -> should be mapped to 2nd pin (0x06)
Refactor the port mapping logic to allow to take the above
differences into account. Fixes issues with HDAudio on some
TGL platforms.
