drm/msm/dpu: remove dpu_hw_fmt_layout from struct dpu_hw_sspp_cfg

Remove dpu_hw_fmt_layout instance from struct dpu_hw_sspp_cfg, leaving
only src_rect and dst_rect. This way all the pipes used by the plane
will have a common layout instance (as the framebuffer is shared between
them), while still keeping a separate src/dst rectangle configuration
for each pipe.
