[PATCH 05/25] drm/msm/dpu: move pipe_hw to dpu_plane_state

[Dmitry Baryshkov <dmitry.baryshkov@linaro.org>]

In preparation to adding fully virtualized planes, move struct
dpu_hw_pipe instance from struct dpu_plane to struct dpu_plane_state, as
it will become a part of state (allocated during atomic check) rather
than part of a plane (allocated during boot).
