Add MCA we(4) attachment for WD80x3 cards and clones. Tested with
WD8003W/A, card provided by David Brownlee (thanks!). The SMC Elite stuff not tested since I don't have any; hopefully it's correct, should match information in ADF files. The MCA-specific init quirk taken from Linux smc-mca.c driver. I don't quite grok why it works, but it does *cross fingers*. The WD8003W/A seems to be quite a good choice. I get like 340KB/s on my machine, where 3c523 does only like 310KB/s. The numbers would be probably even better with faster CPU than 386DX :)
