[PATCH] dnet: mark methods static and annotate for correct endianness

[PATCH] dnet: mark methods static and annotate for correct endianness

[Harvey Harrison]

Their doesn't appear to be bugs with the endianness handling here, just get the
annotations right to keep sparse happy.

Suppresses the following sparse warnings:
drivers/net/dnet.c:30:5: warning: symbol 'dnet_readw_mac' was not declared. Should it be static?
drivers/net/dnet.c:49:6: warning: symbol 'dnet_writew_mac' was not declared. Should it be static?
