[v3,00/17] 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.
