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).
