This PR takes the latest ath12k driver from upstream, while preserving the 4addr patch that Siklu added. Other Siklu patches were omitted:

• 2739a55 is reworked for the new tree in VER-273: ath12k: fix 4addr multicast packet tx #72
• ca0a9df was not cherry-picked because the behavior was fixed in upstream

This PR was created as follows:

• rm -r drivers/net/wireless/ath/ath12k
• git fetch upstream
• git checkout 19dd0cc36a52d0d121d7854cbb9b00d6d4dcad0a -- drivers/net/wireless/ath/ath12k
• git cherry-pick -n b197f2b
• modify ath12k/qmi.c:3922 from (struct sockaddr_unsized *)sq to (struct sockaddr *)sq since sockaddr_unsized is a recent addition and not available in kernel v6.18.

This PR "squashes" all the upstream changes of ath12k into one commit, therefore it loses any new history. For proper file history visit https://github.com/gregkh/linux/commits/master/drivers/net/wireless/ath/ath12k
