EN7523 is an armv8 based silicon used inside broadband access type devices
such as xPON and xDSL. It shares various silicon blocks with MediaTek
silicon such as the MT7622.

We should add a new subfolder
arm/mach-airoha or add the config in arm/mach-mediatek, as it re-uses part of the MediaTek IP.

Please merge this with 3/14

I also wonder if this actually boots. I suspect we need DT_MACHINE_START() macro and the compatibles defined. It's many years ago I did this for MediaTek but I remember that the system won't boot without that. Maybe things have changed over time though.
