Child nodes of a fixed-partitions node are not necessarily partition
entries, for example an nvmem-layout node has no reg property. The
current code passes a NULL reg pointer and uninitialized len to the
length check, which can result in a kernel panic or silent failure to
register any partitions.

Fix validate_of_partition() to return a skip indicator when no reg
property is present. Guard add_of_partition() with a reg property
check for the same reason.

I think this warrants a Cc: stable and backporting as well as a Fixes tag.
