However, CONFIG_PM means, roughly, "runtime PM or suspend/hibernation support" and some of those functions are useful regardless of that. For example, they are used by the ACPI fan driver for controlling fans and acpi_device_set_power() is called during device removal. Moreover, device initialization may depend on setting device power states properly. For these reasons, make the routines manipulating ACPI device power states defined in drivers/acpi/device_pm.c available for CONFIG_PM unset too.

However, there can be only one such register in the system and it really should be saved after non-boot CPUs have been offlined and restored before they are put back online during resume. For this reason, move the saving and restoration of BUS_MASTER_RLD to syscore suspend and syscore resume, respectively, and drop the no longer necessary suspend/resume callbacks from the ACPI processor driver.

When it is set, it indicates that the ACPI event, either GPE or fixed event, is associated with a handler. Update the comments to reflect this flag.

There is no functional change to acpi_device_set_id() in this patch. acpi_pnp_type is added to acpi_device_pnp, so that PNPID type is self-contained within acpi_device_pnp. acpi_add_id(), acpi_bay_match(), acpi_dock_match(), acpi_ibm_smbus_match() and acpi_is_video_device() are changed to take acpi_handle as an argument, instead of acpi_device.
