drm/format-helper: Streamline blit-helper interface

commit 06905637428ce1fbee90812dd0b6430dd71aa7e7 from
https://nv-tegra.nvidia.com/r/3rdparty/canonical/linux-jammy.git

 jetson_36.3

Move destination-buffer clipping from format-helper blit function into
caller. Rename drm_fb_blit_rect_dstclip() to drm_fb_blit_toio(). Done for
consistency with the rest of the interface. Remove drm_fb_blit_dstclip(),
which isn't required.
