Implement basic WoW functionalities such as magic-packet, disconnect
and pattern. The logic is very similar to ath11k.
When WoW is configured, ath12k_core_suspend and ath12k_core_resume
are skipped (by checking ar->state) as we are not allowed to power
cycle firmware.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4

Currently, when debug logs are enabled, messages such as the following
are found in the kernel log:
event mgmt rx skb pK-error len 209 ftype 00 stype 50
The "pK-error" comes from using %pK to display an skb address in an
interrupt context.
Per the guidance in the current "printk-formats" documentation, %pK
"is only intended when producing content of a file read by userspace
from e.g. procfs or sysfs, not for dmesg."
So replace %pK with %p in all of the ath12k_dbg() format strings.

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:

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