arm64: dts: exynos: gs101: define USI8 with I2C configuration
USI8 I2C is used to communicate with an eeprom found on the battery
connector. Define USI8 in I2C configuration.
USI8 CONFIG register comes with a 0x0 reset value, meaning that USI8
doesn't have a default protocol (I2C, SPI, UART) at reset. Thus the
selection of the protocol is intentionally left for the board dts file.
