This allows using this parser with any flash driver that takes care of
setting of_node (using mtd_set_of_node helper) correctly. Up to now
support for "fixed-partitions" DT compatibility string was working only
with flash drivers that were specifying "ofpart" (manually or by letting
mtd use the default set of parsers).

This matches existing bindings documentation.
