Another "virtual" clock (in the sense that it isn't configurable). This
could possibly be done as a clock in the device tree, but I think this is a
bit cleaner.

checkpatch still complains about this one, but I don't see any reason to
break it up even further. It doesn't make sense to me to split the header

Changes in v2:
