Introduce a new helper to tell if device (node) is compatible to the
given string value. This will help some drivers to get rid of unneeded
OF APIs/etc and in may help others to be agnostic to OF/ACPI.

While doing it, I have noticed that ACPI_DEVICE_CLASS() macro seems
defined in unsuitable location. Move it to the better one.

Last patch is an example of what the first two are doing.

The entire series can go, I believe, via ACPI (linux-pm) tree in case
the last patch gets tag from the respective maintainer.

In v2:
- updated commit message and added kernel doc for a new API (Greg)
- also replaced acpi_device_get_match_data() with the agnostic API
- tried to keep header inclusions ordered (to some extent)

Andy Shevchenko (3):
  ACPI: Move ACPI_DEVICE_CLASS() to mod_devicetable.h
  device property: Implement device_is_compatible()
  ata: ahci_platform: Make code agnostic to OF/ACPI
