vboot: Add config to enable EC EFS support 

This patch makes coreboot set VBSD_EC_EFS flag if CONFIG_VBOOT_EC_EFS
is set. Depthcharge/Vboot uses this flag to determine whether it can
update EC when it's already running a RW copy.

BUG=b:65028930
BRANCH=none
TEST=Verify soft sync runs successfully on Fizz.
