[PATCH v6 4/8] arm64: dts: ti: k3-j722s: Switch to k3-am62p-j722s-common-{}.dtsi includes

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.

v5:
https://lore.kernel.org/r/20240604085252.3686037-5-s-vadapalli@ti.com/
Changes since v5:
- Rather than including "k3-am62p-j722s-common.dtsi" which is the
  equivalent of "k3-am62p.dtsi" in the current series, k3-j722s.dtsi
  includes "k3-am62p-j722s-common-{}.dtsi" and "k3-j722s-main.dtsi".
  Also, to match the J7 family of SoCs, the CPU, Cache and CBASS-Ranges
  are included in "k3-j722s.dtsi".
