acpi/pstate: Support Integer _PSD

Standard _PSD should be package, while some buggy BIOSes will use Integer
for _PSD, e.g. Gigbyte's GA-H67MA-UD2H-B3.

Following template is used for Integer _PSD, after I have fiddled
around with the hw.acpi.cpu sysctl tree a little bit:
- Coordination is set to software all
- The integer of _PSD is taken as the power domain number
- The number of CPUs in the power domain is updated when new CPU in that
  power domain is seen
