USB1 controller on J722S and AM62P are from different vendors.
Redefine the USB1 node description for J722S by deleting the
node inherited from AM62P dtsi.

v2:
https://lore.kernel.org/r/20240513114443.16350-3-r-gunasekaran@ti.com/
No changes since v2.

v1:
https://lore.kernel.org/r/20240429120932.11456-3-r-gunasekaran@ti.com/
Changes since v1:
- The entire node which was added in k3-j722s.dtsi in v1 in now moved to
  k3-j722s-main.dtsi as USB is a main domain peripheral.
- Used generic node names - renamed "cdns-usb@f920000" to "usb@f920000".

This is odd and indicates issues with current DT file inclusion.
We need to split out the non common IPs (e.g. USB) out of the common k3-am62p-main.dtsi file Maybe call it k3-am62-main-common.dtsi.
Only keep am62p specific stuff in k3-am62p-main.dtsi.

Include k3-am62-main-common.dtsi and k3-am62p-main.dtsi for AM62P
Include k3-am62-main-common.dtsi and k3-j722s-main.dtsi for J722S

This way you don't need to call /delete-node/

Ok. I will move the common nodes between k3-am62p-main.dtsi and
k3-j722s-main.dtsi to "k3-am62p-j722s-common.dtsi".
