I've implemented the registration using soc_device_register() but I've
postponed to a later stage, these registers are in block I need to add
later also for the clocks.

This showed to be also the only user of the early io mapping, which is
now gone.

I'll respin the patchset as soon as you suggest what to do with the
clock-frequency of the system timer.
