drm/fb-helper: Calculate damaged area in separate helper
Add drm_fb_helper_memory_range_to_clip(), a helper function that
accepts an linear range of video memory and converts it into a
rectangle. The computed rectangle describes the damaged area in
terms of scanlines and pixels per scanline.
While at it, make the code more readable by using struct drm_rect
and related helpers.
The code was previously part of the deferred I/O helpers, but is
also useful for damage handling of regular write operations. Update
the deferred I/O code to use the new function.
v2:
* rename helper (Javier)
