To enable WLAN ath10k snoc needs to send the host and target
copy engine info and driver operation mode to WLAN firmware.
The WLAN firmware configure the hardware component according
to the configure request send by ath10k snoc host driver.
Add QMI service to support this WLAN enable and disable
feature for the ath10k snoc WLAN driver.

Add support to configure the bus and wlan copy engine
component. Register event notifier to communicate with
the WLAN firmware over qmi communication interface.
Define data structure and method to process the QMI service
arrive, exit, msa ready and firmware event.
This feature adds support to maintain the SSR state machine
and ath10k core restart handler for the ath10k snoc driver.

Commit 6cd18e711d "block: destroy bdi before blockdev is
unregistered." moved bdi unregistration (at that time through
bdi_destroy()) from blk_release_queue() to blk_cleanup_queue() because
it needs to happen before blk_unregister_region() call in del_gendisk()
for MD. SCSI though will free up the device number from sd_remove()
called through a maze of callbacks from device_del() in
__scsi_remove_device() before blk_cleanup_queue() and thus similar races
as described in 6cd18e711d can happen for SCSI as well as reported by
Omar [1].
Moving bdi_unregister() to del_gendisk() works for MD and fixes the
problem for SCSI since del_gendisk() gets called from sd_remove() before
freeing the device number.
This also makes device_add_disk() (calling bdi_register_owner()) more
symmetric with del_gendisk().

If host driver fails to probed for the first time, and SSR/PDR
get triggered, as part of PD down uevent is sent to host driver
which inturn set recovery in progress which never gets reset
and the next time on FW Ready host driver is not able
to probe successfully
To fix this add a check if driver is probed or not
before sending the uevent.

If FW is down irrespective of crash, a uevent
is sent to wlan host driver to indicate FW is down.

The ath10k snoc driver is a client to WLAN firmware service
started at Q6. Initial control messages to WLAN firmware is
exchanged through QMI interface. This change also adds
the APIs required for WLAN driver to enable and disable
WLAN at firmware.

This change attempts to abort gating of clocks if a
request to turn-on clocks is pending.
This would in turn avoid turning OFF and back ON the
clocks.
