Now that all users of the systick devices wire up the clock inputs,
use those instead of the system_clock_scale and the hardwired 1MHz
value for the reference clock.
This will fix various board models where we were incorrectly
providing a 1MHz reference clock instead of some other value or
instead of providing no reference clock at all.
