Subject: [PATCH 34/37] of: property: fix #nvmem-cell-cells parsing

From: Michael Walle <michael@...le.cc>

Commit 6a80b3e6fb41 ("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.

Fixes: 6a80b3e6fb41 ("of: property: make #.*-cells optional for simple props")
