[PATCH v3 2/7] arm64: dts: ti: k3-j722s-main: Redefine USB1 node description

[Siddharth Vadapalli]

From: Ravi Gunasekaran <r-gunasekaran@xxxxxx>

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@xxxxxx/
No changes since v2.

v1:
https://lore.kernel.org/r/20240429120932.11456-3-r-gunasekaran@xxxxxx/
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".
