Add code to update feature list with CNSS_WLAN_EN_FEATURE flag
if WLAN_EN gpio is supported, the host indicates to firmware
about the WLAN_EN support via the feature list which is sent as
part of host capability qmi message. This would help firmware
to decouple the PERST in RDDM for MSM targets.

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.

It is observed during some stress tests under very bad thermal
conditions that wlan re-probe can fail after cnss2 probes the
device for the 1st time and then powers it off.
When this happens, the SW_CTRL signal doesn't go high after
cnss2 toggles WLAN_EN.
To avoid such issue, add support for conditional device power
off so power supply will be retained for certain chipsets after
cnss2 probes it for the 1st time.

On device probe, cnss2 should not power off the device in api
cnss_wlan_device_init() because the device either:
1) has already been powered down after it is enumerated by
the pcie probe callback and its related code; or
2) doesn't have to be powered off.
To fix this issue, add code to return directly from
cnss_wlan_device_init() without powering down the device once
cnss_bus_init() returns 0.

Based on the results of some stress tests under very low
temperature, such as -40degC, the AON voltage on some of the
devices can take more than 1.5s to reach zero. And under
such circumstances, wlan device probe can fail if cnss2 turns
on wlan power supply too fast.
To avoid wlan probe failure, increase the value of wlan power
on retry factor to 4 so cnss2 can wait up to 2s during extreme
conditions before probing the device again.
