Allwinner R40 supports two USB host ports shared between a USB 2.0 EHCI
host controller and a USB 1.1 OHCI host controller. Add support for both
of them.
If machine USB support is not enabled, create unimplemented devices
for the USB memory ranges to avoid crashes when booting Linux.

v2: The USB Controllers are part of the chipset, so instantiate them
unconditionally
