[PATCH] of_path: only handle no driver for device if it is on a bus

[Ian Abbott]

This fixes a regression in __of_find_path() for flash devices created by
the cadence-quadspi driver, which do not have 'dev->driver' set.  Such
devices do not have 'dev->bus' set either, so we can use that to qualify
the existing test.
