Add support for Mediatek Wi-Fi7 driver mt7925

This series adds mt7925, a new mac80211 driver for MediaTek Wi-Fi 7 (802.11be) device Filogic 360, which can support Station, AP, P2P, and monitor modes. Filogic 360 supports max 4096-QAM/160MHz radio operation at 6 GHz, 5 GHz, or 2.4 GHz with 2x2 antennas. This chip supports PCIe and USB bus type.

mt7925 supports Wi-Fi 6E and EHT rate with single link only at this moment, whereas Wi-Fi 7 and its specific features are working in progress. They will be introduced in further patches.

The driver is build tested by Intel's kernel test robot with both GCC and Clang with several architecture. Sparse reports no warnings.

There are multiple authors, they are listed in alphabetical order below.

v2:
- add patchwork link for preceding series
- rebase on top of staging tree and apply fixes for following new patches
* 586baa51d755 ("wifi: mt76: remove unused error path in mt76_connac_tx_complete_skb")
* 29b8fc6742a1 ("wifi: mt76: fix race condition related to checking tx queue fill status")
* e8c1841278a7 ("wifi: cfg80211: annotate iftype_data pointer with sparse")

v3:
- rebase on the top of maintainer tree
- align struct ieee80211_chanctx_conf migration to struct mt76_vif
- fix chip_reset fail
- this series is based on "wifi: mt76: move struct ieee80211_chanctx_conf up to struct mt76_vif"
