soc/intel/alderlake: Implement function to map physical port to EC port

Currently coreboot and EC had different logic to interpret TCSS port
number which would break retimer update functionality since coreboot
would pass wrong port information to EC.

To correct this, coreboot has implemented function which converts
coreboot physical port mapping to EC's abstract port mapping.

Each SoC needs to implement this weak function since only SoC will have
correct physical port mapping data. This function should resolve issue
of port mismatch since coreboot will count only enabled ports and
provide correct EC port number in return.

BUG=b:207057940
BRANCH=None
TEST=Check if retimer update works on Redrix and correct port
information is passed to EC.
