Some platform PCIe RC impedance can't achieve the target defined in spec.
It will result to Genoa card link down. To WA the issue, downgrade RC speed
to Gen1 for auto Genoa EP. Because the linkdown issue may happen during
enum, and before enumunation we do not know EP device ID, so set init
speed to Gen1, and then restore speed to default for others wifi chip.
The change does not affect Genoa throughput, because Gen1 speed is enough
for Genoa.

Cnss2 driver receives cnss_pci_smmu_fault_handler cb from smmu
driver whenever wlan fw access illegal IOVA address. In
cnss smmmu fault cb handler, cnss2 driver rings trace stop
door bell register to stop tracing in wlan fw. This will
help to get proper traces to debug where illegal access
is happening in wlan fw.

It costs 4M when loading cnss2, if device id is QCA6490 and enabled
CONFIG_CNSS2_DEBUG. Which is big memory consumption for low rate issue
debugging. So add CONFIG_DISABLE_CNSS_SRAM_DUMP to disable sram_dump.

Support CONFIG_CNSS_REQ_FW_DIRECT compile flag passing
from external to use request_firmware_direct instead of
firmware_request_nowarn to avoid regdb.bin search failure
with qcn7605 that finally cause kernel panic on the LV
platform.

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.

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.

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.

at boot and WLAN resume sequence after WLAN HW is enabled.
