[PATCH 3/6] cdev: export cdevfs_add_partition for general use

[Ahmad Fatoum]

__devfs_add_partition was added, so it can internally be used by
functions that already have a cdev and don't require looking it up first
by file path. This is useful elsewhere as well, so give it a less
internal-sounding name and start exporting it.
