arcnet: com90io: Use arcnet_<I/O> routines
Simplify and make consistent the current uses of inb/outb by using the newly introduced arcnet_<I/O> equivalents. o Add new #defines for register offsets o Remove old #defines that included the ioaddr o Remove obfuscating macros by expanding them in-place where appropriate Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Michael Grzeschik <m.grzeschik@pengutronix.de>
