software node: Fix device_add_software_node()

The function device_add_software_node() was meant to
register the node supplied to it, but only if that node
wasn't already registered. Right now the function attempts
to always register the node. That will cause a failure with
nodes that are already registered.

Fixing that by incrementing the reference count of the nodes
that have already been registered, and only registering the
new nodes. Also, clarifying the behaviour in the function
documentation.

- xhci features and bugfixes

- dwc3 features added for more hardware support

- dwc2 fixes and new hardware support

- cdns3 driver updates for more hardware support

- gadget driver cleanups and minor fixes

- usb-serial fixes, new driver, and more devices supported

- thunderbolt feature additions for new hardware

- lots of other tiny fixups and additions

The chrome driver changes are in here as well, as they depended on
some of the typec changes, and the maintainer acked them.

All of these have been in linux-next for a while with no reported

software node: Provide replacement for device_add_properties()

At the moment the function device_del() is calling
device_remove_properties() unconditionally. That will result into the
reference count of the software node attached to the device being
decremented, and in most cases it will hit 0 at that point. So in
practice device_del() will unregister the software node attached to
the device, even if that was not the intention of the caller. Right
now software nodes can not be reused or shared because of that.

So device_del() can not unregister the software nodes unconditionally
like that. Unfortunately some of the users of device_add_properties()
are now relying on this behaviour. Because of that, and also in
general, we do need a function that can offer similar behaviour where
the lifetime of the software node is bound to the lifetime of the
device. But it just has to be a separate function so the behaviour is
optional. We can not remove the device_remove_properties() call from
device_del() before we have that new function, and before we have
replaced device_add_properties() calls with it in all the places that
require that behaviour.

This adds function device_create_managed_software_node() that can be
used for exactly that purpose. Software nodes created with it are
declared "managed", and separate handling for those nodes is added to
the software node code. The reference count of the "managed" nodes is
decremented when the device they are attached to is removed. This will
not affect the other nodes that are not declared "managed".

The function device_create_managed_software_node() has also one
additional feature that device_add_properties() does not have. It
allows the software nodes created with it to be part of a node
hierarchy by taking also an optional parent node as parameter.

media: software_node: Add support for fwnode_graph*() family of functions

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".

Registering software_nodes with the .parent member set to point to a
currently unregistered software_node has the potential for problems,
so enforce parent -> child ordering in arrays passed in to

Software nodes that are children of another software node should be
unregistered before their parent. To allow easy unregistering of an array
of software_nodes ordered parent to child, reverse the order in which
