In addition to MT7603E PCI devices, the driver supports the WLAN core on
MT7628/MT7688, which needs to be defined in DT.

This driver is for a newer generation of 2x2 MediaTek 802.11n chipsets.
MT7603E is a PCIe chip.
MT7628 and MT7688 are MIPS SoC devices with built-in WLAN.
MT7688 is limited to 1x1
This driver fully supports AP, station, mesh, ad-hoc and monitor mode.
