Subject: [PATCH v2 2/3] arm64: dts: ti: k3-j722s-main: Redefine USB1 node description

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.

Signed-off-by: Ravi Gunasekaran <r-gunasekaran@...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@...0000" to "usb@...0000"

v1: https://lore.kernel.org/all/20240429120932.11456-1-r-gunasekaran@ti.com/
