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.
