There's no SRAM support for uio_pruss to be handled for AM33xx, but I
will be posting a separate series with the DT portion and some alternate
hard reset handling implementation. I find the private OMAP reset api to
be very ugly but we might have to go with that for now. I didn't want
the OMAP hard reset portion to hold up the more important part of this
cleanup.
