of_path: Fix bug with partitions, simply code

In commit 75b682795eafb2385556a9642f09e0af96a1264a using a path that
has a partition description broke.

Fix this and simpfy the code some.

There is no need to loop over each string in the path property:  it's
defined to have at most one parition description, no extant dts has
more than one, and how it would handle more than one didn't make sense
anyway.

Once not looping, __of_find_path() just needs the partition
description text, not both the original node and property name to look
it up from.

When using a partition description, don't lookup the cdev of the node
just to replace it with the partition's cdev.
