This change enables support for generating ACPI nodes for I2C tunnel for any GOOG0012 device that is sitting behind the Chrome EC. It accepts a config "remote_bus" which allows mainboard to configure the id of the remote bus that is being tunneled. BUG=b:154290952 BRANCH=None TEST=Verified that SSDT node for I2C tunnel behind Chrome EC is generated correctly.
