[PATCH 6/6] ARM: dts: microchip: sama7d65_curiosity: add EEPROM

[<Ryan.Wanner@microchip.com>]

From: Ryan Wanner <Ryan.Wanner@microchip.com>

If the MAC address is not fetched and loaded by U-boot then Linux will
have to load the address. The EEPROM and nvmem-layout to describe
EUI48 MAC address regions.
