mcu: Add new min_schedule_time() and max_nominal_duration() helpers
Add a function that returns the minimum amount of time the host needs
to reserve for messages to be sent from host to micro-controller.
Add a function that returns the maximum amount of time (in seconds)
that all micro-controllers should be able to schedule future timers
at.
