wifi: ath12k: hal_rx: Use memset_startat() for clearing queue descriptors
In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memset(), avoid intentionally writing across neighboring fields.
Use memset_startat() so memset() doesn't get confused about writing beyond the destination member that is intended to be the starting point of zeroing through the end of the struct and fixes the below clang warning.
Warning: include/linux/fortify-string.h:314:4: warning: call to '__write_overflow_field' declared with 'warning' attribute: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Wattribute-warning]

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.
