EFS2: Verify and jump when system shuts down in RO
Currently, when the system shuts down in RO, EC resets with AP_OFF
flag. This was for allowing the EC to jump to RW and get ready for
the next normal boot after a system shuts down from the recovery
mode (chromium:1045209).
This behavior causes the reboot from the recovery mode to be stopped
(b:154778457).
This patch makes RO jump to RW instead of resetting with AP_IDLE
flag. After sysjump, the AP can continue to sequence up or down.
