drm/simpledrm: Enable FB_DAMAGE_CLIPS property

commit d3901a2603625ef06b21d498fe8f4a09aa0c5296 from
https://nv-tegra.nvidia.com/r/3rdparty/canonical/linux-jammy.git jetson_36.3

Enable the FB_DAMAGE_CLIPS property to reduce display-update
overhead. Also fixes a warning in the kernel log.

  simple-framebuffer simple-framebuffer.0: [drm] drm_plane_enable_fb_damage_clips() not called

Fix the computation of the blit rectangle. This wasn't an issue so
far, as simpledrm always blitted the full framebuffer. The code now
supports damage clipping and virtual screen sizes.

v3:
	* fix drm_dev_enter() error path (Noralf)
	* remove unnecessary clipping from update function (Noralf)
