smcs lan91c111 patch

Hi,

I've been working on smsc lan driver a little and I decided to post my work to the comunity. Please report any comments regarding this patch. I had to add these modifications to get smsc lan chip on my PXA board working without DEBUGging messages.

Basicly it :
-adds autorelease functionality for smsc chip
-does save/restore of registers being shared among different actions inside the chip (PTR and PNR registers), according to datasheet -and does some checks.

CHANGELOG:
* Patch by Hinko Kocevar 20 Mar 2004
- Add auto-release for SMSC LAN91c111 driver
- Add save/restore of PTR and PNR regs as suggested in datasheet

rgrds, himba

..because under Linux "if something is possible in principle,
then it is already implemented or somebody is working on it".

Fine, I'll try to test your code with my Nios boards next week.
