    lynxpoint: Route all USB ports to XHCI in finalize step
    
    This commit adds a new Kconfig option for the LynxPoint
    southbridge that will have coreboot route all of the USB
    ports to the XHCI controller in the finalize step (i.e.
    after the bootloader) and disable the EHCI controller(s).
    
    Additionally when doing this the XHCI USB3 ports need
    to be put into an expected state on resume in order to make
    the kernel state machine happy.
    
    Part of this could also be done in depthcharge but there
    are also some resume-time steps required so it makes sense
    to keep it all together in coreboot.
    
    This can theoretically save ~100mW at runtime.
    
    Verify that the EHCI controller is not found in Linux and
    that booting from USB still works.
