Adding OpenWrt Support for Netgear RAX120 (Nighthawk AX12)

Just tried it and it still didn't work. After applying both parts of the fix, 5G radios are still low powered. 2.4G has proper power output. Also of note, part 2 of the fix deletes cal-ahb0000.bin. This file gets recreated when rebooting.
Edit: Just to add, I am using the NSS build for RAX120 posted here: Qualcommax NSS Build
