[PATCH] ARM: dts: stm32: Add phandle to nvmem efuse into STM32MP13xx ethernet DT node

[Marek Vasut]

The efuses on STM32MP13xx can be populated with ethernet MAC address.
Add the nvmem-cells/nvmem-cell-name DT properties to ethernet MAC DT
nodes to describe the placement of both MAC address fields within the
efuses, so the ethernet MAC driver can access the efuses and populate
the correct MAC address into the hardware.
