Rafał Miłecki c5330723d5 dt-bindings: nvmem: move deprecated cells binding to its own file
Support for old NVMEM fixed cells was deprecated in favour of
"fixed-layout". It's still part of the nvmem.yaml though and may be
unknowingly used by new bindings added without much of analyze.

To make it more difficult to accidentally support old syntax move its
binding to separated file with "deprecated" in its name.
