[PATCH 2/3] dt-bindings: nvmem: brcm, nvram: add NVMEM cell to example

From: Rafał Miłecki <rafal at milecki.pl>

NVRAM doesn't have cells at hardcoded addresses. They are stored in
internal struct (custom & dynamic format) . It's still important to
define relevant cells in DT so NVMEM consumers can reference them.

One of cells set in almost every device is "et0macaddr" containing MAC
address. Add it to example to show how it can be referenced.
