[PATCH 3/4] platform/chrome: cros_ec_typec: Stash port driver info

[Prashant Malani]

Stash port number and a pointer to the driver-specific struct in the
local Type-C port struct.

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