arm64: dts: apple: j314/j316: Disable ATC3_USB_AON power domain

These power domains are normally always on for real Thunderbolt ports
(or else dwc3 breaks), but not for the port that's hardwired to the HDMI
bridge.

Fixes some dmesg spam:

apple-pmgr-pwrstate 292280000.power-management:power-controller@a0:
    always-on domain atc3_usb_aon is not on at boot
