arm64: dts: apple: t8103: Mark ATC USB AON domains as always-on

Browse Source 
Shutting these down breaks dwc3 init done by the firmware. We probably
never want to do this anyway. "always-on" is a plausible interpretation
of the "aon" suffix.
The t8112, t600x and t602x "ps_atc?_usb_aon" power-controller nodes are
have already "apple,always-on" properties.
