	KVM: x86: deprecate -M kernel-irqchip=off except for -M isapc ... 
			The userspace local APIC is basically untested and does not support many
features such as TSC deadline timer, x2APIC or PV spinlocks.  On the
other hand, the PIT and IOAPIC are okay as they are not tied to
the processor and are tested with -M kernel-irqchip=split.
Therefore, deprecate the local APIC and, with it, limit
-M kernel-irqchip=off to the ISA PC machine type, which does not
have a local APIC at all.
