hw/arm/nrf51: Wire up sysclk

Wire up the sysclk input to the armv7m object.

Strictly this SoC should not have a systick device at all, but our
armv7m container object doesn't currently support disabling the
systick device.  For the moment, add a TODO comment, but note that
this is why we aren't wiring up a refclk (no need for one).
