x86_acpi_cstates: Port to the new ACPI and CPUIDLE APIs.

Tested by OscarL and confirmed to be working on at least
one machine, though on others it hangs, so leaving out
of the default builds for now.

This adds an "acpi_processor_id" field to x86 arch_cpu_info,
gleaned from the MADT, so we can match our cpu_ents to ACPI
processor objects. (FreeBSD does a similar mapping, see
their acpi_cpu_probe method.)
