ARM: dts: renesas: Enable sysinfo on R-Car V3H Condor/Condor-I

Browse source 
Add new sysinfo IDs for R-Car V3H Condor/Condor-I .

Enable support for sysinfo on R-Car V3H Condor/Condor-I. 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 r8a77980.dtsi already.
        Drop status = "okay" from EEPROM node.
	Add dts: tag.
	Update the commit message, note the new sysinfo IDs.
	Fix Kconfig EEPROM address to be 0x50 and match the DT, sync config.]
