[v2,1/3] ACPI: Move ACPI_DEVICE_CLASS() to mod_devicetable.h

The data type of struct acpi_device_id is defined in the
mod_devicetable.h. It's suboptimal to require user with
the almost agnostic code to include acpi.h solely for the
macro that affects the data type defined elsewhere.

Taking into account the above and for the sake of consistency
move ACPI_DEVICE_CLASS() to mod_devicetable.h.

Note, that with CONFIG_ACPI=n the ID table will be filed with data
but it does not really matter because either it won't be used, or
won't be compiled in some cases (when guarded by respective ifdeffery).

The first patch can be applied independently. But it may be better to apply
all three via one tree (linux-pm was mentioned in the cover letter) as it
shows the point.

Probably better if you take the whole thing. But if needed, I can take this
through the ata tree.
