Add support for the MediaTek latest generation IEEE 802.11ax 4x4 device MT7915E, which supports concurrent dual-band operation at both 5GHz and 2.4GHz. Note that this patch just add basic part and will add more HE capabilities support in the further patches. The driver supports AP, Station, Mesh and monitor mode.
