Cobalt over Dovetail represents time values as counts of nanoseconds,
dismissing the legacy (hardware) TSC representation entirely. For this
reason, we can move any code which implements TSC/nanosecs conversion
to the I-pipe specific section.

This includes the handler applying CPU frequency updates
(xnclock_update_freq()) which has no purpose over Dovetail, since
these events are transparently dealt with for the proxy device by the
generic clockevent framework.

No functional change is introduced.
