Update "k3-j722s.dtsi" to include "k3-am62p-j722s-common-{}".dtsi files in
order to reuse the nodes shared with AM62P. Also include the J722S specific
"k3-j722s-main.dtsi".

Since the J7 family of SoCs has the k3-{soc}.dtsi file organized as:
k3-{soc}.dtsi = CPU + Cache + CBASS-Ranges + "Peripheral-Includes"
switch the "k3-j722s.dtsi" file to the same convention.
