Mitsuru IWASAKI 51b6d45826 Refine implementation of PowerResource manipulation sub-routines.
- Add new funcions for device state stuff;
   acpi_get_current_device_state() and acpi_set_device_state()
 - Add new funcions for power resource stuff;
   acpi_powerres_init(), acpi_powerres_debug(),
   acpi_get_current_powerres_state() and acpi_set_powerres_state()

These were implemented based on 7.1, 7.2, 7.2.2, 7.2.3, 7.2.4, 7.3,
7.3.3, 7.4, 7.4.1, 7.4.2, 7.4.3 and 7.5 of ACPI spec 1.0b.
