Fix misfiring of DEV SOL interrupt during enable_irq().
Ignore DEV SOL interrupt in case of device power off
as it is expected as part of off sequence.
In case of HOST triggered recovery, CNSS driver
tries to put device to RDDM first using MHI_SYS_ERR
and HOST_RESET_REQUEST if MHI_SYS_ERR fails. With
SOL enable, replace HOST_RESET_REQUEST with HOST_SOL.

Add support to configure log level for dmesg and
ipc logging. Default log level is set to DEBUG
for ipc logging and INFO for dmesg logging.
Change default behavior of cnss_pr_dbg and
cnss_pr_vdbg API to not print in dmesg.

User may configure such runtime_pm debugfs unexpected during test,
add the log to explicitly show what is configured.

Currently, the cnss2 platform driver just can support
one wlan device attached, so do the following changes
to cover dual wlan card attach case. Firstly, delay
the second device go to pcie link suspend and power
off state to make sure it really finished the pcie
enumeration. Then pcie enumeration succeeds with
multi-devices. Secondly, supporting to write the qrtr
node instance id to PCIE register for wlan fw reading,
which can fix qmi message exchange failure if active
two Hastings devices. Thirdly, change the usage of
plat_env to support dual Hastings.

Some auto HW can't guarantee wlan_en low state when powerup.
Add a macro to enable initializing wlan_en state.

DMS server runs in Modem. When Modem SSR happens dms_del_server
gets called. Even after DMS service disconnected, qmi_txn_wait is
still waiting. Release DMS QMI handle in dms_del_server to cancel
pending transaction.

If Device boots up in secure mode, CNSS defers PCI enumeration,
calibration and host driver registration. When secure mode exits
host driver gets notified from CTRL_PARAM and calls PLD API to
perform previously deferred operations and enable WLAN HW. This
can take some seconds and by the time again Secure mode can enter,
disable WLAN and access controlled by TZ.
Now Calibration completes and CNSS receives CAL_DONE indication.
As part of CAL_DONE when CNSS try to power off WLAN access WLAN_EN
it results in NOC error.
One more scenario, where CNSS can access WLAN_EN when WLAN HW
is disabled by TZ, could be when QMI message times out. Consider
secure mode is entering as part of CNSS will to IDLE shutdown.
During IDLE shutdown while sending MODE_OFF QMI message to FW
it might wait for 10 seconds if FW does not respond. But TZ has
timeout of 5 sec if framework does not respond in 5 Sec TZ will
disable WLAN_EN and access control it. Now when after QMI timedout
when try to access WLAN_EN it results in NOC error.
Check secure peripheral state before updating WLAN_EN and maintain
correct driver state in such scenario.

WLAN HW can be securely disabled. Add support in platform driver to
handle WLAN cold boot initialization sequence changes if HW is disabled
at boot and WLAN resume sequence after WLAN HW is enabled.

Debugfs item control_params can be used to disable|enable
drv suspend, since FW can configure suspend mode only before FW ready,
so host needs make sure this flag is set at proper phase.

AOP Mbox interface message is updated to include the PDC name as WLAN
devices like KIWI needs 2 PDCs.
Also following updates are done:
1. Always open Mbox channel for OL CPR update.
2. Add device tree config for PDC - VReg mapping and
WLAN device PDC Init table.
3. Reconfig PDC based on WLAN device connected to the platform.
4. Add debug interface for PDC update.

WLAN driver register requires calibration to complete if enabled.
Calibration timeout can happen due to FW or file system mount delay.
Update driver to assert only for calibration timeout due to FW.
In some cases file system mount may take longer if file system repair
is attempted. Thus update cnss platform driver to wait for this
operation to complete and only log the time elapsed.

The side-band SOL (Sign-Of-Life) GPIOs are introduced to help make
RDDM more reliable so that device dump can be copied correctly. When
device SOL GPIO is triggered from device, it means there is watchdog
reset happened in device and driver should expect RDDM to happen.
When host SOL GPIO is triggered from host, it will result watchdog
reset as well as PCIe controller reset in device which should try to
enter RDDM always. This commit also adds debug hooks for the GPIOs.

Bring CNSS family drivers from msm-5.10 kernel as of commit
cc3bc4b888af (cnss2: Fix a few switch statement fallthrough
issues) to WLAN platform project. Fix SPDX-License format for
a few files as well.
drivers/net/wireless/cnss* -> .
include/net/cnss* -> inc/
Above shows how directories and header files are relocated.
