lynxpoint: Finalize chipset before playload if not CONFIG_CHROMEOS

The Chrome OS environment sends an SMI to finalize the chipset/board
    at the end of the "depthcharge" payload, but there is no facility to
    send this command if not using the full ChromeOS firmware stack.

This commit adds a callback before booting the payload that will
    issue this SMI which will lock down the chipset and route USB devices
    to the XHCI controller.
