PVH guests have no DM, so this causes the guest to fetch the online CPU
bitmap from an unbacked 0xaf00 PIO port when executing the GPE handler.
Seeing how ACPI CPU hotplug is the only event delivered via GPE, remove
the GPE handler in addition to anything ACPI CPU hotplug related.
This shrinks PVH's DSDT substantially and prevents spuriously executing
a large amount of AML with no purpose at all.
