The current sbsa-ref cannot use EHCI controller which is only able to do 32-bit DMA, since sbsa-ref doesn't have RAM below 4GB. Hence, this uses XHCI to provide a usb controller with 64-bit DMA capablity instead of EHCI.
Please also modify hw/arm/Kconfig file so SBSA-ref will select XHCI instead of EHCI there.
