tcpm: Add configuration struct for tcpc i2c params
Add a new configuration struct tcpc_config_t that initially defines the
i2c host port and i2c slave address of all TCPCs present on the board.
This will allow us to create boards with multiple TCPCs on different i2c
ports, with arbitrary i2c slave addresses.
BUG=chromium:551078
TEST=Manual on glados. Verify PD communication / charging is still
functional on both PD ports.
BRANCH=None
