Merge: wifi: ath12k: fix unbind operation

MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10/-/merge_requests/78

JIRA: https://issues.redhat.com/browse/RHEL-70414

ath12k driver to handle new WiFi 7 devices by Qualcomm was already enabled.
This MR includes the necessary fixes to able to unbind and use the workaround to allow working from VMs (https://gitlab.com/jtornosm/jtornosm_tools). Final development for that is being long and could require firmware support.
