The Freescale hypervisor does not allow guests to write to the timebase
registers (virtualizing the timebase register was deemed too complicated),
so don't try to synchronize the timebase registers when we're running
under the hypervisor.
This typically happens when kexec support is enabled.

e500mc cannot doze or nap due to an erratum (as well as having a
different mechanism than previous e500), but it has a "wait" instruction
that is similar to doze.
On 64-bit, due to the soft-irq-disable mechanism, the existing
book3e_idle should be used instead.
