Subject: [PATCH v4 2/7] 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.
