Robert Marko 359a6e36e9 mac80211: ath11k: sync with ath-next
Synchronize the ath11k backports with the current ath-next tree.

All of the changes are various bugfixes, there is no new major feature.
Notable bugfixes are:
* WCN6855 board name fixes
* One MSI vector booting is working again
This is rather important for most of the older platforms.

* DFS CAC state in virtual interfaces was fixed
* TX power during CAC reporting

Subject: [PATCH] wifi: ath11k: ath11k_debugfs_register(): fix
format-truncation warning
In v6.6-rc4 with GCC 13.2 I see a new warning:
drivers/net/wireless/ath/ath11k/debugfs.c: In function 'ath11k_debugfs_register':
drivers/net/wireless/ath/ath11k/debugfs.c:1597:51: error: '%d' directive output may be truncated writing between 1 and 3 bytes into a region of size 2 [-Werror=format-truncation=]
drivers/net/wireless/ath/ath11k/debugfs.c:1597:48: note: directive argument in the range [0, 255]
drivers/net/wireless/ath/ath11k/debugfs.c:1597:9: note: 'snprintf' output between 5 and 7 bytes into a destination of size 5
Increase the size of pdev_name to 10 bytes to make sure there's enough room for
the string. Also change the format to '%u' as ar->pdev_idx is u8.
Compile tested only.
