[PATCH v3 12/12] arm64: dts: exynos: gs101: enable eeprom on gs101-oriole

Enable the eeprom found on the battery connector.

The selection of the USI protocol is done in the board dts file because
the USI CONFIG register comes with a 0x0 reset value, meaning that USI8
does not have a default protocol (I2C, SPI, UART) at reset.
