mb/google/rex/deku: Define TCSS port and EC port mapping

Browse source 
Deku design has a non-sequential mapping between CPU Type-C ports
and EC Typec-C ports. This patch maps the CPU Type-C port to the
correct EC Type-C port for the Intel re-timer driver.

BUG=b:399032094
TEST=Check the Type-C port and EC port mapping in coreboot log

deku-rev1 ~ # cbmem -c |grep "USB Type-C"
[INFO ]  USB Type-C 0 mapped to EC port 0
[INFO ]  USB Type-C 1 mapped to EC port 2
[INFO ]  USB Type-C 2 mapped to EC port 1
[INFO ]  USB Type-C 3 mapped to EC port 3
