fwk: store the ac_boot status in the EC ROM

In the standalone mode, bbram will be cleared if the user removes the
adapter, so the system can not pwoer on via ac attach.

This change stores the ac_boot status in the EC ROM, even if the mainboard
no power , EC still can get the correct status

BRANCH=fwk-main
BUG=https://app.clickup.com/t/86eqmw497
TEST=Enable stanalone operation and power on AC attach, the system can
     power on via AC attached without battery
TEST=Disable stanalone operation and power on AC attach, the system can
    power on via AC attached without battery
TEST=Disable stanalone operation and power on AC attach, the system can
    power on via AC attached with battery
