generic: backport fix for #nvmem-cell-cells false warning
Recent backport of NVMEM layout support as well as acommpanying OF changes
introduced a false #nvmem-cell-cells warning as #nvmem-cell-cells are
fully optional.

So, backport an upstream fix for this.

Subject: [PATCH] of: property: fix #nvmem-cell-cells parsing
Commit 67b8497f005f ("of: property: make #.*-cells optional for simple
props") claims to make the cells-name property optional for simple
properties, but changed the code for the wrong property, i.e. for
DEFINE_SUFFIX_PROP(). Fix that.
