ACPI: add processor driver for Xen virtual CPUs.

Because the processor is controlled by the VMM in xen,
we need new acpi processor driver for Xen virtual CPU.

Specifically we need to be able to pass the CXX/PXX states
to the hypervisor, and as well deal with the peculiarity
that the amount of CPUs that Linux parses in the ACPI
is different from the amount visible to the Linux kernel.
