[PATCH 3/3] ARM: dts: renesas: Enable sysinfo on R-Car D3 Draak

[Marek Vasut]

From: Tam Nguyen <tam.nguyen.xa at renesas.com>

Enable support for sysinfo on R-Car D3 Draak board. The sysinfo is used
e.g. to access and decode board-specific information and then in turn
used by board-info to print those information.

[Marek: Drop compatible from I2C node, this is in r8a77995.dtsi already.
        Drop status = "okay" from EEPROM node.
	Add dts: tag.
	Fix Kconfig EEPROM address to be 0x50 and match the DT, sync config.]
