Bring in the basic infrastructure necessary for enabling htt_stats via debugfs.
Patch series bring support to request stats type to firmware, dump the stats
and request to reset the stats from firmware.
Schema with one ath12k device:
ath12k
`-- pci-0000:06:00.0
|-- mac0
`-- htt_stats
|-- htt_stats_type
|-- htt_stats_reset

Depends-On: [PATCH v2] wifi: ath12k: Fix pdev id sent to firmware for single phy devices
Link: https://lore.kernel.org/linux-wireless/20240621102809.3984004-1-quic_rgnanase@xxxxxxxxxxx/T
v6:
- Error code changes while writing type to htt_stats_type debugfs
- Added new line as an argument to print_array_to_buf()
- Rebased on ToT
v5:
- Addressed Jeff comments
- Changed sizeof type with data structure pointer.
- Pulled out patch #3 from series.
- Rebased on ToT
v4:
- No changes. Re-sending due to mail issue.
v3:
- Addressed Kalle's comments
- Locking is taken care. ar::data_lock is used to protect stats
request completion and other HTT debug entities protected using
ar::conf_mutex.
- Fixed KASAN warning from WCN7580 during stats type write.
- Changed header style for MU PPDU stats printing routine
- Renamed function ath12k_debugfs_htt_stats_init() to
ath12k_debugfs_htt_stats_register()
- Added expected length check while parsing each tag to prevent
buffer overread.
v2:
- Handled pdev id sent in HTT stats request command for WCN7850
Added changes as a separate patch #3
- Tested in WCN7850 and added Tested-on tag
- Rebased on ToT
