hw/arm: Add EHCI/OHCI controllers to Allwinner R40 and Bananapi board

Browse source 
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.
