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.

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.

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.
