wifi: ath12k: Add peer extended Rx statistics debugfs support

Currently, peer extended Rx statistics are not supported. Therefore, expose
peer extended Rx statistics support through debugfs, allowing users to
enable or disable the collection of statistics information. After that
the statistics information can be dumped through debugfs. Below are the
debugfs commands exposed.

Enable/Disable:
echo <1/0> > /sys/kernel/debug/ieee80211/phyX/ath12k/ext_rx_stats

Dump:

wifi: ath12k: add factory test mode support

Add support to process factory test mode commands(FTM) for calibration.
By default firmware start with MISSION mode and to process the FTM commands
firmware needs to be restarted in FTM mode using module parameter ftm_mode.
The pre-request is all the radios should be down before starting the test.

All ath12k test mode interface related commands specified in enum
ath_tm_cmd.

When start command ATH_TM_CMD_TESTMODE_START is received, ar state
is set to test Mode and FTM daemon sends test mode command to wifi
driver via cfg80211. Wifi driver sends these command to firmware as
wmi events. If it is segmented commands it will be broken down into
multiple segments and encoded with TLV header else it is sent to
firmware as it is.

Firmware response via UTF events, wifi driver creates skb and send
to cfg80211, cfg80211 sends firmware response to FTM daemon via
netlink message.

Command to boot in ftm mode
insmod ath12k ftm_mode=1

be enabled using menuconfig. Dump collected for a radio is 55 MB
approximately.

Currently, ath12k does not support Time-Average-SAR (TAS). In order to enable
TAS read the tables from ACPI and send them to the firmware using
WMI_PDEV_SET_BIOS_INTERFACE_CMDID command. Besides, ath12k registers an ACPI
event callback so that ACPI can notify ath12k to get the updated SAR power
table and sends it to the firmware when the device state is changed.

ACPI is only enabled for WCN7850 using struct ath12k_hw_params::acpi_guid
field. Most likely QCN9274 will never support ACPI as the chip is not used in
laptops.

wifi: ath12k: implement handling of P2P NoA event

The Notice of Absence (NoA) attribute is used by the P2P Group Owner to
signal its absence due to power save timing, concurrent operation, or
off-channel scanning. It is also used in the P2P Presence Request-Response
mechanism.

The NoA attribute shall be present in the P2P IE in the beacon frames
transmitted by a P2P Group Owner when a NoA schedule is being advertised,
or when the CTWindow is non-zero.

So add support to update P2P information after P2P GO is up through
event WMI_P2P_NOA_EVENTID, and always put it in probe resp.

Create p2p.c and p2p.h for P2P related functions and definitions.

wifi: ath12k: add firmware-2.bin support

Firmware IE containers can dynamically provide various information
what firmware supports. Also it can embed more than one image so
updating firmware is easy, user just needs to update one file in
/lib/firmware/.

The firmware API 2 or higher will use the IE container format, the
current API 1 will not use the new format but it still is supported
for some time. Firmware API 2 files are named as firmware-2.bin
(which contains both amss.bin and m3.bin images) and API 1 files are
amss.bin and m3.bin.

Currently ath12k PCI driver provides firmware binary (amss.bin) path to
MHI driver, MHI driver reads firmware from filesystem and boots it. Add
provision to read firmware files from ath12k driver and provide the amss.bin
firmware data and size to MHI using a pointer.

Currently enum ath12k_fw_features is empty, the patches adding features will
add the flags.

wifi: ath12k: driver for Qualcomm Wi-Fi 7 devices

ath12k is a new mac80211 driver for Qualcomm Wi-Fi 7 devices, first
supporting QCN9274 and WCN7850 PCI devices. QCN9274 supports both AP
and station; WCN7850 supports only station mode. Monitor mode is not
(yet) supported. Only PCI bus devices are supported.

ath12k is forked from an earlier version of ath11k. It was simpler to
have a "clean start" for the new generation and not try to share the
code with ath11k. This makes maintenance easier and avoids major
changes in ath11k, which would have significantly increased the risk
of regressions in existing setups.

ath12k uses le32 and cpu_to_le32() macros to handle endian
conversions, instead of using the firmware byte swap feature utilized
by ath11k. There is only one kernel module, named ath12k.ko.

Currently ath12k only supports HE mode (IEEE 802.11ax) or older, but
work is ongoing to add EHT mode (IEEE 802.11be) support.

The size of the driver is ~41 kLOC and 45 files. To make the review
easier, this initial version of ath12k does not support Device Tree,
debugfs or any other extra features. Those will be added later, after
ath12k is accepted to upstream.

The driver is build tested by Intel's kernel test robot with both GCC
and Clang. Sparse reports no warnings. The driver is mostly free of
checkpatch warnings, albeit few of the warnings are omitted on
purpose, list of them here:

https://github.com/qca/qca-swiss-army-knife/blob/master/tools/scripts/ath12k/ath12k-check#L52

The driver has had multiple authors who are listed in alphabetical
order below.
