Subject: [PATCH V4 2/4] dt-bindings: nvmem: convert base example to use NVMEM fixed cells layout

From: Rafał Miłecki <rafal@...ecki.pl>

With support for the "fixed-layout" binding it's possible and preferred
now to define fixed NVMEM cells in the layout node. Do that for the
binding example binding.
