[PATCH v7 3/8] arm64: dts: ti: k3-j722s: Add main domain peripherals specific to J722S

Introduce the "k3-j722s-main.dtsi" file to contain main domain peripherals
that are specific to J722S SoC and are not shared with AM62P. The USB1
instance of the USB controller on J722S is different from that on AM62P.
Thus, add the USB1 node in "k3-j722s-main.dtsi".
