ACPI: add ACPI bus_type for driver model
Add ACPI bus_type for Linux driver model.
1. .shutdown method is added into acpi_driver.ops
needed by bus_type operations.
2. remove useless parameter 'int state' in .resume method.
3. change parameter 'int state'
to 'pm_message_t state' in .suspend method.
Note: The new .uevent method mark ACPI drivers by PNPID instead of by name.
Udev script needs to look for "HWID=" or "COMPTID=" to load
ACPI drivers as a result.
