The timers are always part of the SoC, so they should always be enabled,
and if there was some board specific wiring, in that maybe one of the
times was fed a different clock source than iprocslow, we could deal
with that on a per-board basis.

If someone does not want a specific timer to be used, it could be
unbound once the kernel has booted for instance.
