arm64: dts: rockchip: Enable USB ports on Radxa ROCK 2A/2F

The ROCK 2A has three USB 2.0 Type-A HOST ports behind an onboard
USB hub, and one USB 3.0 Type-A port.

And the ROCK 2F has two USB 2.0 Type-A HOST ports behind an onboard
USB hub, and one USB 2.0 Type-C OTG port.

Add support for using the USB ports on Radxa ROCK 2A/2F.

The onboard USB hub handles OHCI so only the EHCI controller is enabled.
