Merge: Wireless core and drivers rebase to v6.15

MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/merge_requests/6948

JIRA: https://issues.redhat.com/browse/RHEL-89168

ARK MR: cki-project/kernel-ark!3897

Tested: basic testing with several supported WiFi cards (Intel, Qualcomm, Mediatek and Realtek).

Wireless core and drivers update to v6.15.
MHI will be updated in a separate way.

Upstream status: linux.git

Not necessary because SKB_DROP_REASON_SUBSYS_OPENVSWITCH is still the same:
Omitted-fix: 1cc3462 selftests: openvswitch: don't hardcode the drop reason subsys

Commented fix was already included:
Omitted-fix: 175e69e wifi: iwlwifi: restore missing initialization of async_handlers_list

Not important fixes (postponed):
Omitted-fix: 9a353a4 wifi: ath12k: avoid burning CPU while waiting for firmware stats
Omitted-fix: ac7b8ff wifi: ath12k: don't use static variables in ath12k_wmi_fw_stats_process()
Omitted-fix: ad5e917 wifi: ath12k: don't wait when there is no vdev started
Omitted-fix: 54c3500 wifi: ath12k: Fix double budget decrement while reaping monitor ring

Fixes for AP capabilities (postponed):
Omitted-fix: 64cbf0d wifi: mt76: mt7996: Fix possible OOB access in mt7996_tx()
Omitted-fix: a0c5eac wifi: mt76: Assume __mt76_connac_mcu_alloc_sta_req runs in atomic context
Omitted-fix: c772cd7 wifi: mt76: Move RCU section in mt7996_mcu_set_fixed_field()
Omitted-fix: 28d519d wifi: mt76: Move RCU section in mt7996_mcu_add_rate_ctrl_fixed()
Omitted-fix: 3dd6f67 wifi: mt76: Move RCU section in mt7996_mcu_add_rate_ctrl()
Omitted-fix: 7153257 wifi: mt76: Remove RCU section in mt7996_mac_sta_rc_work()
Omitted-fix: e8d7eef wifi: mt76: mt7996: Fix secondary link lookup in mt7996_mcu_sta_mld_setup_tlv()
Omitted-fix: a59650a wifi: mt76: mt7996: Fix valid_links bitmask in mt7996_mac_sta_{add,remove}
