WLAN IOMMU mappings have cached attribute set whereas
ADSP IOMMU mappings do not have cached attribute set.
This is resulting in an inconsistent memory view between
ADSP SS and WLAN SS. ADSP writes to a DDR location and
WLAN HW reads from the same location but since access is
cached from WLAN side, there is a possibility of reading
incorrect values.
Fix is to use IOMMU_CACHE flag for audio smmu mappings.

PM_SUSPEND_PREPARE. Once it happens, the count of cnss_pm_sem will
be abnormal.
And, ROME firmware download is in qcacld driver. Not in cnss driver.
So, remove function cnss_pm_notify, and the export symbol cnss_lock_pm_sem
and cnss_release_pm_sem. Move the protection to qcacld driver. In qcacld
driver, use wakeup source to protect ROME firmware download.

Converge dt nodes for wlan chips that share the same PCI slot
into one node.
The items in this node are split into 2 parts: common and chip
specific.
The common part will be parsed during cnss probe, such as basic
power related configuration and bus type, to power on the device
and trigger pci probe;
Chip specific part will be parsed during bus specific probe, this
part includes chip specific power and feature related
configurations.
With this change, cnss2 can support different chips on one pci
slot with the same image.

In some scenario like ssgtzd get killed, CNE and TZ go out of sync.
Consider a case where TZ notified CNE to enable WLAN HW. Now CNE
will request to CNSS to Enable WLAN HW. At the same time again TZ
notified CNE to Disable WLAN HW but due ssgtzd killed, CNE did not
wait for previous request(sent to CNSS to enable WLAN HW) and immediately
return to TZ. TZ assumes everything is done and change state to secure
mode. Now CNSS act on previous request of enabling WLAN HW but when
when checks the state it get secure mode and fails to enable WLAN
and asserts. Avoid assert in such scenarios.

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.

2) Add one more vreg config, 'vdd-wlan-rfa3', into the vreg list

3) Add one more dts parameter, 'qcom,multi-wlan-exchg' into the
wlan device tree node on auto platforms, to reflect the fact
that multiple wlan chipsets can be plugged, while only one of
them exists at a time.
Also, reorder the parameters passed for debug printing in function

The side-band SOL (Sign-Of-Life) GPIOs are introduced to help make

device SOL GPIO is triggered from device, it means there is watchdog
