net: dm9000x: use standard I/O accessors
The current dm9000x driver accesses its memory mapped registers directly
instead of using the standard I/O accessors. This can cause problems on
Blackfin systems as the accesses can get out of order. So convert the
direct volatile dereferences to use the normal in/out macros.
