slimbus: core: fix of_slim_get_device() kernel doc

Unlike slim_get_device() the of_slim_get_device() helper does not
allocate and register any slimbus devices in case lookup fails.

Update the of_slim_get_device() kernel doc to reflect this and add a
comment about the helper taking a reference to the returned device.
