Daisuke Nojiri 7630636a0f vboot: Verify and jump to RW_A or RW_B ...

This patch gives EC the capability of verifying and jumping to
RW_A or RW_B. EC tries the slot stored in a persistent storage
(e.g. BBRAM). If verification fails due to invalid contents, EC
tries the other slot. AP's expectation and its reaction to the
state of the slots and the currently running image are summarized
below.

Since the system is still unlocked (CONFIG_SYSTEM_UNLOCKED), EC
won't try to verify or jump to RW yet.

          |       AP expects X
----------+---------------------------
SLOT_A=X  |         proceed
SLOT_B=X  |         proceed
----------+---------------------------
SLOT_A=X' |       reboot to B
SLOT_B=X  |         proceed
----------+---------------------------
SLOT_A=X  |         proceed
SLOT_B=X' |       reboot to A
----------+---------------------------
SLOT_A=X' | write X to B, reboot to B
SLOT_B=X' | write X to A, reboot to A

BUG=b:38462249
BRANCH=none
TEST=Lock the system and boot Fizz on barrel-jack and type-c.
