[PATCH 12/23] of: partitions: force "partitions" subnode

[Sascha Hauer <s.hauer@pengutronix.de>]

The binding states that a subnode containing partition subnodes
should have the name "partitions". Enforce this so that we do not
parse nodes with other names which may have partition descriptions
for other disks.
