TCPMv2: Add support for combination of PPC & non-PPC ports
Some PD/TCPC chips have integrated power path control, this CL allows
having combination of chips with discrete PPC and integrated PPC in
same board. By checking board level function to see if board's port
has PPC or not, logic decides to call PPC functions.
BUG=none
BRANCH=none
TEST=Tested on ADL-RVP, CCGXX with integrated PPC &
NCT3808 with discrete SN5S330 PPC combo works.
