iwasaki 861bb3822c Add x86/acpica/acpi_wakeup.c for amd64 and i386. Difference of
suspend/resume procedures are minimized among them.

common:
- Add global cpuset suspended_cpus to indicate APs are suspended/resumed.
- Remove acpi_waketag and acpi_wakemap from acpivar.h (no longer used).
- Add some variables in acpi_wakecode.S in order to minimize the difference
  among amd64 and i386.
- Disable load_cr3() because now CR3 is restored in resumectx().

amd64:
- Add suspend/resume related members (such as MSR) in PCB.
- Modify savectx() for above new PCB members.
- Merge acpi_switch.S into cpu_switch.S as resumectx().

i386:
- Merge(and remove) suspendctx() into savectx() in order to match with
  amd64 code.
