haswell: Add pei_data field for USB routing
The linux kernel will unconditionally route all USB
ports to the XCHI controller at boot. The EHCI controller
can then be disabled, and it should be left disabled
by the reference code when this is done.
However not all OS may do this unconditional route,
so provide an option to the reference code binary to
enable this behavior.
