In the current solution wil6210 configures the vring in a worker
and holds only one pending CID. This implementation may lead to
race conditions between connect and disconnect events of multiple
stations or fast connect/disconnect events of the same station.
In order to allow the removal of the connect worker and handling of
WMI_VRING_CFG_DONE_EVENTID in the connect event, the WMI replies
that provide the reply in a given buffer needs to be handled
immediately in the WMI event interrupt thread.
To prevent deadlocks, WMI replies that requires additional
handling are still handled via the events list.

In TX vring allocation, vring_tx->va is allocated before WMI command to
configure the vring is sent to the device. As the WMI command can take
time to complete, it can lead to scenarios where vring_tx->va is not NULL
but vring is still not enabled.
This patch adds a check that vring_tx_data is enabled before returning
a valid TX vring.

wil_vring_fini_tx is called in disconnect in order to free the
allocated vrings.
wil_vring_fini_tx is disabling the vring_tx_data before napi_synchronize
is called in order to avoid the tx handling of this vring, while
wil_vring_free is called only after napi finished the current handling
of the tx completed packets.
Due to that, in case of disconnect, wil6210_netdev_poll_tx can be called
when vring->va is not NULL but vring_tx_data[i]->enabled is already
disabled.
This patch checks vring_tx_data[i]->enabled in wil6210_netdev_poll_tx
to prevent handling of disabled vrings.

In the start_ap/change_beacon API, when we set up probe response
offloading, we only use the IE list from the probe response
template and not the IE list from the proberesp_ies argument.
As a result, we miss important IEs and it causes problems with
some scenarios such as P2P.
With this change, we merge the list of IEs from the probe response
template and proberesp_ies and send the merged list to the FW
for offloading. It is still FW responsibility to filter out
irrelevant IEs when sending probe response, based on the actual
contents of the probe request.
Also in case association response termplate is not provided,
we will use the merged list of IEs from probe response in the
association response as well.

Currently the privacy flag calculation in change_beacon
checks for RSN IE inside proberesp_ies, but normally it
is not found there. It works today because of code inside
the function wil_fix_bcon, but wil_fix_bcon is not directly
related to change_beacon, and it may be changed or removed
in the future and break the calculation.
To fix this issue, change the privacy flag calculation
to check RSN IE inside the beacon itself. The new check is more
reliable and will not be sensitive to changes in wil_fix_bcon.

Added a simple interface for platform to perform crash
recovery.
When firmware crashes, wil driver can notify the platform
which can trigger a crash recovery process. During
the process the platform can request a ram dump
from the wil driver as well as control when firmware
recovery will start. This interface allows the platform
to implement a more advanced crash recovery, for
example to reset dependent subsystems in proper order, or
to provide its own notifications during the recovery process.

In __wmi_send we check if fw is ready at the beginning of the function.
While we wait for the completion of the previous command, system suspend
can be invoked and reset the HW, causing __wmi_send to read from HW

Taking the wmi_mutex in the reset flow when setting the FW ready bit
to zero will prevent the above race condition.

msm root-complex does not maintain parent/child relationship
with PCIe devices. Due to this, suspend operation may be carried
out asynchronously between PCIe device and root-complex.
In cases where 11ad refuses to suspend for any reason, the
root-complex connected to it may get suspended in parallel,
causing inconsistency between root-complex and 11ad device.
Disabling async suspend ensures proper ordering of suspend
