Dovetail exports integrated services for proxying the host tick, which
requires no specific interface for managing the hardware timer beyond
the common clockevents interface.

Likewise, the monotonic and realtime clocks can be read directly from
the out-of-band stage via the regular kernel calls available from NMI
context (ktime_get_mono_fast_ns(), ktime_get_real_fast()).

Move the related support to the I-pipe section, we won't need it for
Dovetail.

No functional change is introduced.
