rockchip: rk3588-generic: Move usb nodes to board dts

After the commit 7a53abb183 ("rockchip: rk3588: Remove USB3 DRD nodes
in u-boot.dtsi") was merged for v2024.10 there is no reason to keep the
usb nodes for the Generic RK3588 board in the board u-boot.dtsi.

Move usb related nodes from board u-boot.dtsi to main board device tree.

While at it, also drop use of the usb3-phy as we only want to enable the
usb2-phy to be compatible with as many boards as possible.
