Adding OpenWrt Support for Netgear RAX120 (Nighthawk AX12)

I am curious if anyone has played around more with IRQ balancing on top of the commit here. Seems like some of the WiFi instability I had way earlier was from changing CPU assignments for IRQs that really should not be changed. It was just poking around from my side since this router and WiFi was not my daily driver and had only limited attention. I see that currently the snapshot version is reported by community members to be very stable, and only some IRQs are re-distributed (as per the commit above).

The IRQ balancing topic for IPQ807x has already been touched upon in other threads and seems like there are a lot of IRQs that should not be touched, maybe even most of them. I am just curious if somebody already had the curiosity and time to dig deeper here and have some more info.
