This patchset implements XHCI on sbsa-ref board to replace EHCI.
As sbsa-ref does not have DRAM below 4G, it cannot utilize EHCI 
that only has 32-bit DMA capablity. Now this board has XHCI as 
an available usb controller with 64-bit DMA capablity.

History:
v1 -> v2:
- rebased on master as v1 did not applied
- moved pcd setting in dec file into the first commit

Define the pcd settings for identifying the base address of XHCI
and XHCI's mmio size, and remove relevant EHCI settings.

As sbsa-ref board uses xhci to replace ehci, the DSDT is updated to match
the platform xhci controller. This also removes previous ehci structure.
