Hi,
this series converts all existing users of of_graph_get_next_endpoint that pass
a non-NULL prev argument to the function and decrement its refcount themselves
to stop doing that. The of_node_put is moved into of_graph_get_next_endpoint
instead.
This allows to add a for_each_endpoint_of_node

Decrementing the reference count of the previous endpoint node allows to
use the of_graph_get_next_endpoint function in a for_each_... style macro.
Prior to this patch, all current users of this function that actually pass
a non-NULL prev parameter should be changed to not decrement the passed
Note that while of_graph_get_next_endpoint decrements the reference count
of the child node passed to it, of_node_put(child) still has to be called
manually when breaking out of the loop.

Changes since v1:
- Added a comment about the child
In preparation for the following patch, stop decrementing the endpoint node
refcount in the loop. This temporarily leaks a reference to the endpoint node,
which will be fixed by having of_graph_get_next_endpoint decrement the refcount
of its prev argument instead.
