dma_slave_config direction field was marked as deprecated sometime back,
though no new users are being added, some old ones still persist.

So, here is first set of removal batch, please test and ack.

Some drivers and users are next to be done.

One note on renasas drivers, I found it bit difficult to remove it due
to usage of a layer between drivers, so if some Renasas folks can patch
these drivers, it would be great

I have not heard any objections, so merging this with ACKs/tested
received.

Upon closer look, none of this is used anymore on Renesas ARM SoCs, only
on legacy SuperH SoCs.

So I'd like to defer this to the SuperH maintainers, and people who do have
old SH hardware.

Thanks!

Gr{oetje,eeting}s,
