net: mac8390: Allow modular build

Browse Source 
The modular driver supports only one card, just like the built-in
driver.

Note that this limitation is a problem which affects all Nubus card
drivers, because they have to do all their own bus matching, because
Nubus still lacks the necessary driver model support.
