Added below mentioned changes to support qca6174 in cnss2 driver.
1. While resuming pci link, restore the pci config space before
enabling pci device.
2. Add 10ms delay between wlan_en become active and pcie reset
de-assert.
3. For wlan chipsets which don't support cold boot calibration,
schedule Wlan driver load in cnss_cold_boot_cal_start_hdlr.

Before CNSS2 triggers RDDM mode in device it collects shadow
register dump in a global variable. Now when device moves to
RDDM, shadow registers will be reset. Reading shadow registers
in RDDM mode will override previously read correct values with
reset values. To avoid it, do not dump shadow register in RDDM
mode.

CNSS2 registers as both platform and PCI driver. PCI
device can be removed via sysfs exposed by kernel during
PCI device creation. When PCI device gets removed, CNSS
PCI remove ops gets called. In cnss_pci_remove, unregister

device.

The reservation mode of interrupts in kernel assigns a dummy vector
when the interrupt is allocated and assigns a real vector when the
request_irq is called. The reservation mode helps to ease vector
pressure when devices with a large amount of queues/interrupts
are initialized, but only a minimal subset of those queues/interrupts
is actually used.
So on reservation mode, the msi_data may change after request_irq
is called, so reads msi_data again after mhi request_irq is called,
and then the correct msi_data is programmed into hardware components.
Without this change, spurious interrupt occurs in case of one MSI
vector.

Some platforms can't meet the number of MSI interrupt vectors that
wlan driver requires.
Add one MSI interrupt vector support.
If CONFIG_ONE_MSI_VECTOR is not defined, wlan driver fails to load
if reuired MSI vector allocation fails. It is current behavior.
If CONFIG_ONE_MSI_VECTOR is defined, firstly it will allocate multiple
MSI vectors based on MSI config. If MSI vector allocation fails, it
fallbacks to one MSI vector automatically.

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.

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.
