Move stride programming to dpu_hw_sspp_setup_sourceaddress(), so that
dpu_hw_sspp_setup_rects() programs only source and destination

This separation is logically correct, but there is another codepath
using this.
_dpu_plane_color_fill() calls pdpu->pipe_hw->ops.setup_rects.
So for solid fill, I presume that stride getting programmed is 0 as
there is no buffer to fetch from.
But with this separation, we will miss re-programming stride and it will
remain at the old value even for solid fil cases?
You might want to add setup_sourceaddress call there? But that wont make
sense either because for solid fill there is nothing to fetch from.
Perhaps, another op for stride programming then?
