baytrail: Add ACPI Device for XHCI 

This will allow USB devices to wake the system (if 5V is not turned off)
and the controller to enter D3 at runtime. (if autosuspend is enabled)

BUG=chrome-os-partner:23629
BRANCH=baytrail
TEST=build and boot on baytrail

1) with modified EC to leave 5V on in S3 ensure that waking from suspend
with USB keyboard works.
2) with laptop-mode-tools usb autosuepend config updated see that device
enters D3 at runtime when no external devices attached.
