[PATCH 2/2] nvmem: Drop now unnecessary partition quirk

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

The nvmem core uses container_of() on the cdev to retrieve its driver
data. For partitions the nvmem core tried to retrieve the master cdev
first. This is no longer necessary since the devfs-core now passes the
master cdev as context pointer and not the partition cdev.

This also fixes a bug when a partition was partitioned again. In this
case we would have to iterate upwards until we find the master cdev
instead of doing only one level.
