drm/atomic-helper: Move DRM_PLANE_HELPER_NO_SCALING to atomic helpers

The macro DRM_PLANE_HELPER_NO_SCALING is only useful with the interfaces
in drm_atomic_helper.h, but defined in drm_plane_helper.h. So half of
DRM includes the latter header file for using this macro. Move the macro
and remove the include statements.
