wlan_platform: Bring initial files for CNSS family drivers

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.

+config CNSS2
+	tristate "CNSS2 Platform Driver for Wi-Fi Module"
+	depends on !CNSS && PCI_MSM
+	select CNSS_PLAT_IPC_QMI_SVC
+	help
+	  This module adds the support for Connectivity Subsystem (CNSS) used
+	  for PCIe based Wi-Fi devices with QCA6174/QCA6290 chipsets.
+	  This driver also adds support to integrate WLAN module to subsystem
+	  restart framework.
+
+config CNSS2_DEBUG
+	bool "CNSS2 Platform Driver Debug Support"
+	depends on CNSS2
+	help
+	  This option is to enable CNSS2 platform driver debug support which
+	  primarily includes providing additional verbose logs for certain
+	  features, enabling kernel panic for certain cases to aid the
+	  debugging, and enabling any other debug mechanisms.
+
+config CNSS2_QMI
+	bool "CNSS2 Platform Driver QMI support"
+	select CNSS_QMI_SVC
+	depends on CNSS2
+	help
+	  CNSS2 platform driver uses QMI framework to communicate with WLAN
+	  firmware. It sends and receives boot handshake messages to WLAN
+	  firmware, which includes hardware and software capabilities and
+	  configurations. It also sends WLAN on/off control message to
+	  firmware over QMI channel.
+
+config CNSS_ASYNC
+	bool "Enable/disable CNSS platform driver asynchronous probe"
+	depends on CNSS2
+	help
+	  If enabled, CNSS platform driver would do asynchronous probe.
+	  Using asynchronous probe will allow CNSS platform driver to
+	  probe in parallel with other device drivers and will help to
+	  reduce kernel boot time.
+
+config BUS_AUTO_SUSPEND
+	bool "Enable/Disable Runtime PM support for PCIe based WLAN Drivers"
+	depends on CNSS2
+	depends on PCI
+	help
+	  Runtime Power Management is supported for PCIe based WLAN Drivers.
+	  The features enable cld wlan driver to suspend pcie bus when APPS
+	  is awake based on the driver inactivity with the Firmware.
+	  The Feature uses runtime power management framework from kernel to
+	  track bus access clients and to synchronize the driver activity
+	  during system pm.
+	  This config flag controls the feature per target based. The feature
+	  requires CNSS driver support.
+
+config CNSS_QCA6290
+	bool "Enable CNSS QCA6290 chipset specific changes"
+	depends on CNSS2
+	help
+	  This enables the changes from WLAN host driver that are specific to
+	  CNSS QCA6290 chipset.
+	  These changes are needed to support the new hardware architecture
+	  for CNSS QCA6290 chipset.
+
