The size of structure imx_rproc_att_imx7d and imx_rproc_att_imx6sx have
not changed nor has there been an addition of new imx_rproc_att that would
justify the change.

It seems to me you are working on something internally and this patch is in
preparation for that.  If that is the case then please resubmit this patch with
the rest of the code.

Thanks,
