system: Add EC_RESET_FLAG_EFS
This patch adds EC_RESET_FLAG_EFS. It indicates EC jumped to RW by
successfully running EFS.
system_jumped_late can be used to avoid running some code twice
(once in RO and again in RW). Such code is currently (wrongly)
guarded by system_jumped_to_this_image.
BUG=b:156101251, chromium:1072743
BRANCH=none
TEST=Verified the bug is fixed.
