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:
v2 -> v3:
- remained the original USB hierarchy in DSDT
- changed two usb ports from type A to type C
- refactored patchset
v1 -> v2:
- rebased on master as v1 did not applied
- moved pcd setting in dec file into the first commit
