To be honest, I'm not too happy about the way you specify a single
register for each clock as a global 'reg' property.

Presumably each of these registers is part of an IP block that does
multiple things, so it would be better to start out with a binding
for each IP block. How many of these blocks are used for clocks, and
what do they do?
