bbu: add flag for enabling eMMC boot ack
bbu_mmcboot_handler() already takes care to switch $mmc.boot to the
freshly read inactive partition. On some SoCs like the STM32MP1, this is
not enough, but the boot ack bit must be set as well, so the BootROM can
communicate with the eMMC.
Have this happen as part of the eMMC boot switch after a successful
update if bbu_data::flags has BBU_FLAG_MMC_BOOT_ACK set.
