Add support for QRTR to forward messages between network clusters. The
network subnet id's are attached to the QRTR subnodes in the MHI and
RPMSG/GLINK nodes.
The current forwarding decisions are done based on the net ids and are
wrapped in a single function for easier maintenance of forwarding
decisions later on. The function will return true once it determines
a subnet has no connection to another subnet.
The NEW_SERVER, DEL_SERVER, and DEL_CLIENT control messages should be
forwarded while the DATA and RESUME_TX commands should be passed along
to their destination node.
The nameservice is expected to send NEW_SERVER commands for it's entire
database instead of just the local service database with these changes.
This is to make sure new nodes get service notifications that came
earlier and were meant to be forwarded to the new node.
This change squashes the following commits from msm-4.14:
commit e5f6a6769ceb ("net: qrtr: Add forwarding support based on net id")
commit 4516ab18718d ("net: qrtr: avoid deadlock in case of recursive
lock for node list")
commit dc2d47cd12d3 ("net: qrtr: Only update pkts with broadcast node
ID")
commit 4277aebeff91 ("net: qrtr: Free skb if qrtr_node_lookup fails
during qrtr_fwd_pkt")
In addition fix minor format issues and update copyright.

There is a requirement where slimbus slave don't expect ports
to be disconnected during stream unprepare for sample rates
other than 44.1/88.2k, which is causing mute issues.
Added new slim_stream_unprepare_disconnect_port API to support
disconnect port request from clients without freeing port memory
allocated during stream prepare.

There will be non-atomic work associated with receiving the tx resume
packet from the remote. Move the handling to work function context in
preparation for the non-blocking socket blocking improvement.
In system heavy load cases the rx work queued in global worker queue is
getting delayed and causing clients request timeouts.
Create and use separate worker thread to process qrtr rx packets.

synchronize_rcu() is slow and can create delays on creating/removing
sockets.
Some clients have latency requirements for spinning off a
thread that creates a client and lookup sockets for some sessions. They
close the lookup socket during this sequence which causes delays. Each
call to synchronize_rcu takes 20-40 ms which is too long.
Remove the rcu logic and change qrtr_port_lock to a spinlock so it can
be used in qrtr_port_lookup which may be used in atomic context.

If a port tries to send a message before the name service binds to the
control port, then that message should succeed. This will allow clients
to operate normally until the name service comes online and causes a
net reset to restart all the ports.

A dl callback can be received anytime after mhi_prepare_for_transfer
has been called. There is a window where the callback may happen
before the probe initializes the qrtr_mhi_dev state. Move
mhi_prepare_for_transfer after the registering the endpoint.
Once moved, the reverse can happen where qrtr will try to send a packet
before the channels are prepared. Add a wait in the sending path to
ensure the channels are prepared before trying to do a ul transfer.

Ignore the ENODEV failures returned by kernel_sendmsg(). These errors
mean either the local port has closed or the remote has gone down.
Neither of these scenarios are fatal and will eventually be handled
through packets that are later queued on the control port.
Also improve the logging messages to print the error code returned by
kernel_sendmsg().
