hw/arm/allwinner-h3: add USB host controller

Browse Source 
The Allwinner H3 System on Chip contains multiple USB 2.0 bus
connections which provide software access using the Enhanced
Host Controller Interface (EHCI) and Open Host Controller
Interface (OHCI) interfaces. This commit adds support for
both interfaces in the Allwinner H3 System on Chip.
