On faster MCUs the step and unstep events may be too close for the
stepper motor driver. Add a CONFIG_NO_UNSTEP_DELAY build option and
support the case where it is not set. This allows faster MCUs to
schedule two events for each step (one for the step and one for the
unstep).

Some boards may not support hardware based PWM. Update the build so
that those commands do not need to be compiled if they are not
available.

Some boards may not support SPI transfers. Update the build so that
those commands do not need to be compiled if they are not available.
