[PATCH 1/1] hw/arm/sbsa-ref: use XHCI to replace EHCI

[wangyuquan1236@phytium.com.cn]

From: Yuquan Wang <wangyuquan1236@phytium.com.cn>

The current sbsa-ref cannot use EHCI controller which is only
able to do 32-bit DMA, since sbsa-ref doesn't have RAM above 4GB.
Hence, this uses XHCI to provide a usb controller with 64-bit
DMA capablity instead of EHCI.
