lynxpoint: Don't enable SMI handling of TCO

Browse source 
We have no good reason to be handling the TCO timeout
as an SMI since we aren't doing anything special with it
and clearing the status in the handler prevents the reboot
from actually happening.

BUG=chromium:321832
BRANCH=falco,peppy,wolf,leon,beltino,panther,monroe,samus
TEST=boot and read PMBASE+30h and check that bit13 is clear
