dt-bindings: nvmem: brcm,nvram: add basic NVMEM cells
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.
Update binding to allow including basic cells as NVMEM device subnodes.
