MA-14916-10 fix fastboot reboot bootloader issue

In Android, the reboot bootloader flag is written to misc partition, in
the boot flow, u-boot will check that message to decide whether enter
fastboot mode or not. To be compatible with the common implemention,
keep the fastboot_set_reboot_flag there and redefine it to avoid the
error return value which block the reboot process.
