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.
