The wifi hotspot on systems with Mediatek MT7921 wifi chip doesn't work.

MediaTek already have the commit 116c69603b01 ("mt76: mt7921: Add AP mode support") upstream. But it's based on kernel 5.18. Mediatek also suggest to add patches https://patchwork.kernel.org/project/linux-mediatek/list/?series=648452 which are already accepted by upstream to fix bugs in AP mode. Enable AP mode on specific kernel versions.

Verified on the machines with MediaTek MT7921 chip.

[Where problems could occur]
The patches are to enable AP mode and and fix related issues on new VIF with AP capability, should have minimal impact to the origin behaviors.

  - Add additional patch suggested by Mediatek ("mt76: mt7921: not support beacon offload disable command")
  - Add required fix back in mt7921_mcu_set_bss_pm() in commit ("mt76: mt7921: fix command timeout in AP stop period")
