This implements the remaining .graph_*() callbacks in the fwnode
operations structure for the software nodes. That makes the
fwnode_graph_*() functions available in the drivers also when software
nodes are used.
The implementation tries to mimic the "OF graph" as much as possible, but
there is no support for the "reg" device property. The ports will need to
have the index in their name which starts with "port@" (for example
"port@0", "port@1", ...) and endpoints will use the index of the software
node that is given to them during creation. The port nodes can also be
grouped under a specially named "ports" subnode, just like in DT, if
necessary.
The remote-endpoints are reference properties under the endpoint nodes
that are named "remote-endpoint".

aa821b2b9269 ("media: MAINTAINERS: Add myself as maintainer of the
Amlogic GE2D driver") introduced a new MAINTAINERS section, but the file
entry points to the wrong location.
Hence, ./scripts/get_maintainer.pl --self-test=patterns warns:

This test has a problem because we want to know if "k" is -1 or a

u32 so if "k == -1" then -1 gets type promoted to UINT_MAX which is
larger than "f->index". I've added an explicit test to check for -1.

The csc/scaler device private struct is released by
ipu_csc_scaler_video_device_release(), which can be called
by video_unregister_device() if there are no users

Therefore, the mutex can't be held when calling
video_unregister_device() as its memory may be freed

Fortunately, the fix is quite simple as no locking
is needed when calling video_unregister_device(): v4l2-core
