Add support for device recovery.
Wen Gong (3):
ath11k: add ath11k_qmi_free_resource() for recovery
ath11k: add support for device recovery for QCA6390
ath11k: add synchronization operation between reconfigure of

I did some quick testing (commit 4716d5bb1e16 in pending branch) and it
does not seem to work for me:
oot@nuc1:~# echo assert > /sys/kernel/debug/ath11k/qca6390\
hw2.0/simulate_fw_crash
root@nuc1:~# iw wlan0 scan
command failed: Connection timed out (-110)

I have sent v4, it is not to fix your fail:)
It added patch "ath11k: fix invalid m3 buffer address".
https://patchwork.kernel.org/project/linux-wireless/cover/20211116041522.23529-1-quic_wgong@xxxxxxxxxxx/
Also there should be a clear ath11k_warn() message when firmware
recovery was successful, I could not find one from patches.
Yes, if recovery succes, it will have "success" log.
