platform/chrome: cros_ec_typec: Stash port driver info

Browse Source 
Stash port number and a pointer to the driver-specific struct in the
local typec port struct.

These can be useful to the port driver to figure out how to communicate
with the Chrome EC when an altmode-driver related callback is invoked
from the Type-C class code.
