Add QMI client driver for Q6 integrated WLAN connectivity subsystem.
This module is responsible for communicating WLAN control messages to

over QMI interface.
“QUALCOMM Messaging Interface”(QMI) provides the control interface
between
components running b/w remote processors with underlying transport
layer
based on integrated chipset(shared memory) or discrete
chipset(PCI/USB/SDIO/UART).
QMI client driver implementation is based on qmi frmework
https://lwn.net/Articles/729924/.
Below is the sequence of qmi handshake.

Does the responsibility of the driver ends here? I mean is this a
driver
for setting up the firmware and then there's something else doing the
actual wifi operation, or does it simply hand over execution to the
common ath10k logic at this point?
From wlan qmi client point of view once wlan qmi service is discovered,
it connects to the service and
does the above handshakes and later it handover the execution to common
ath10k logic.
These handshakes will be done as part of pd restart as well.

I'm missing this last patch in my mailbox, and it would be nice if all
the patches where in-reply-to the cover letter, to make them easier to
find.

Sure, I will take care this while submitting next version of this patch
series.
