The GPU will continually fire interrupts while a fault buffer GET != PUT,
and to stop the spurious interrupts while the handler does its thing, we
were disabling the fault buffer temporarily.
This is not actually a great idea to begin with, and made worse by Volta
resetting GET/PUT when it's reactivated. So, let's not do that.

FB_DAMAGE_CLIPS is an optional plane property to mark damaged regions
on the plane in framebuffer coordinates of the framebuffer attached to
the plane.
The layout of blob data is simply an array of "struct drm_mode_rect".
Unlike plane src coordinates, damage clips are not in 16.16 fixed point.
As plane src in framebuffer cannot be negative so are damage clips. In
damage clip, x1/y1 are inclusive and x2/y2 are exclusive.
This patch also exports the kernel internal drm_rect to userspace as
drm_mode_rect. This is because "struct drm_clip_rect" is not sufficient
to represent damage for current plane size.
Driver which are interested in enabling FB_DAMAGE_CLIPS property for a
plane should enable this property using drm_plane_enable_damage_clips.
v2:
- Input validation on damage clips against framebuffer size.
- Doc update, other minor changes.
