drm: Use device_get_match_data()

Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data in a single step. With this, adjust the
includes to explicitly include the correct headers. That also serves as
preparation to remove implicit includes within the DT headers
(of_device.h in particular).
