libdt: support "partitions" subnode on mtd devices
In case there is an additional "partitions" subnode between the device
itself and its partitions like /soc/spi@?/mram@?/partitions/partition@?
also try the parent of the parent before giving up finding the device
node.
See kernel docs for reference:
