arcnet: arcdevice.h: Add arcnet_readb and arcnet_writeb
Use the same indirection as the other arcnet_<I/O> macros. Neither of these new macros add the BUS_ALIGN use for 8 bit devices on 16 bit busses. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Michael Grzeschik <m.grzeschik@pengutronix.de>
