DMTimer0 is usable only in secure devices only. This timer by default runs
from an inaccurate RC oscillator the frequency of which can be anywhere
from 16-60KHz based on process variations. There is a mux to change the
clock source but the register for the mux can't be modified in GP devices.
(will add this in the changelog)
