[PATCH 2/2] ARM: dts: microchip: sama5d29_curiosity: Add nvmem-layout in QSPI to describe EUI48 MAC address region

[Manikandan Muralidharan]

Add nvmem-layout in QSPI to describe EUI48 MAC address region.
This is useful for cases where U-Boot is skipped and the Ethernet
MAC address is needed to be configured in Linux.
