x86: Initialize drivers in SMM context if needed

This adds a block in the SMI handler to call init functions for
    drivers which may be used in SMM. A static variable is used to
    ensure the init functions are only called once.

BUG=chrome-os-partner:29580
    BRANCH=mccloud
    TEST=Built and booted on mccloud, system no longer hangs when
    pressing power button at the dev mode screen. Also tested on parrot.
