drivers/intel/usb4/retimer: Add function to correct EC port mapping

Currently coreboot interprets TCSS port number as per physical port
number while EC abstracts port number and provides indices as port
number. For example, if TCSS port 1 and 3 are enabled on the board,
coreboot will interpret port numbers as 0 and 2, but since only 2 ports
are enabled in the system EC will assign port numbers as 0 and 1.

This creates a port number mismatch while communicating between EC and
coreboot. This patch addresses issue where SoC can implement function
to map correct EC port as per port enabled in mainboard.

BUG=b:207057940
BRANCH=None
TEST=Check if code compiles successfully. Functionality will work once
function is implemented in SoC code.
