[Intel-gfx] [PATCH v3 22/22] drm: Remove legacy version of get_scanout_position()

[Thomas Zimmermann <tzimmermann@suse.de>]

The legacy version of get_scanout_position() was only useful while
drivers still used drm_driver.get_scanout_position(). With no such
drivers left, the related typedef and code can be removed
