drm/msm/dpu: move rot90 checking to dpu_plane_atomic_check_sspp()

Move a call to dpu_plane_check_inline_rotation() to the
dpu_plane_atomic_check_sspp() function, so that the rot90 constraints
are checked for both SSPP blocks. Also move rotation field from struct
dpu_plane_state to struct dpu_sw_pipe_cfg.
