[RESEND 7/7] fastboot: Implement generic fastboot_set_reboot_flag

[Lukasz Majewski]

Hi Roman,

> It is possible to implement fastboot_set_reboot_flag in a generic way
> if BCB commands are turned on for a target. Using
> bcb_set_reboot_reason allows to do this by simply passing string with
> correct reboot reason that should be handled during next boot process.
> 
> If BCB are turned off, then bcb_set_reboot_reason would simply return
> error, so it won't introduce any new behaviour for such targets.

This patch causes build breaks when I run the CI on azzure. If it is
still needed, please rebase it and resend.
