timer: Allow board code to define its own timer_is_before implementation

Move sched_is_before() from sched.c to timer_is_before() in the board
specific timer code.  This allows the board code to provide its own
definition.

Also, remove the sched_from_us() and sched_read_time() wrapper
functions and change the callers to directly invoke timer_from_us() /
timer_read_time().
