xen/setup: Route halt operations to safe_halt pvop.
With this patch, the cpuidle driver does not load and
does not issue the mwait operations. Instead the hypervisor
is doing them (b/c we call the safe_halt pvops call).
This fixes quite a lot of bootup issues wherein the user had
to force interrupts for the continuation of the bootup.
Details are discussed in:
