soc/intel/common/block/i2c: Scan bridge devices behind I2C controllers
Currently devices behind I2C controllers are scanned using scan_smbus. This is done under the assumption that there are no bridge devices behind I2C controllers. In order to support I2C multiplexers which act as bridge devices and have devices behind them, scan the I2C controllers using scan_static_bus. BUG=b:169444894 TEST=Build and boot waddledee to OS. Ensure that all the bridge devices behind I2C controller are scanned and enabled.
