[PATCH] pcnet32: support boards with multiple phys

Boards with multiple PHYs were not being handled properly by the pcnet32
driver.  This patch by Thomas Bogendoerfer with changes by me will allow
Allied Telesyn 2700FTX and 2701FTX boards to use either the copper or
the fiber interfaces.  It has been tested on ia32 and ppc64 hardware.
Philippe Seewer also tested and improved the patch.
ethtool for pcnet32 already supports multiple phys.
