Subject: [PATCH v6 2/8] arm64: dts: ti: k3-am62p-j722s: Move AM62P specific USB1 to am62p-main.dtsi

The USB1 instance of USB controller on AM62P is different from the USB1
instance of USB controller on J722S. Thus, move the USB1 instance from
the shared "k3-am62p-j722s-common-main.dtsi" file to the AM62p specific
"k3-am62p-main.dtsi" file. Include "k3-am62p-main.dtsi" in "k3-am62p.dtsi".

v5:
https://lore.kernel.org/r/20240604085252.3686037-3-s-vadapalli@ti.com/
Changes since v5:
- Since this v6 series contains "k3-am62p.dtsi" rather than
  "k3-am62p-j722s-common.dtsi", the equivalent change of the v5 patch
  applies to "k3-am62p.dtsi" in the current patch.
- Collected Acked-by tag from Roger Quadros <rogerq@kernel.org>
