Move the call to dpu_format_populate_plane_sizes() to the atomic_check
step, so that any issues with the FB layout can be reported as early as
possible.

At the same time move the call to dpu_format_populate_addrs() to
dpu_plane_sspp_atomic_update(). This way the all layout management is
performed only for the visible planes: the .prepare_fb callback is
called for not visible planes too, so keeping dpu_format_populate_addrs
in dpu_plane_prepare_fb() will require dpu_format_populate_plane_sizes()
to be called for !visible planes too.
