Call AcpiLeaveSleepStatePrep() in interrupt disabled context

(described in ACPICA source code).

- Move intr_disable() and intr_restore() from acpi_wakeup.c to acpi.c
  and call AcpiLeaveSleepStatePrep() in interrupt disabled context.
- Add acpi_wakeup_machdep() to execute wakeup MD procedures and call
  it twice in interrupt disabled/enabled context (ia64 version is
  just dummy).
- Rename wakeup_cpus variable in acpi_sleep_machdep() to suspcpus in
  order to be shared by acpi_sleep_machdep() and acpi_wakeup_machdep().
- Move identity mapping related code to acpi_install_wakeup_handler()
  (i386 version) for preparation of x86/acpica/acpi_wakeup.c
  (MFC candidate).
