skylake: Finalize SMM in coreboot
Once we lock down the SPI BAR we need to tell SMM to re-init its SPI driver or it will be unable to write ELOG events via SMI.
This SMI is also sent at the end of depthcharge so there was just a window where SMI events could get lost.
BUG=chrome-os-partner:50076 BRANCH=glados TEST=enable DEBUG_SMI, boot to dev screen, press power button and see elog events get added without without transaction errors.
