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.
