[U-Boot] [PATCH u-boot git] dm9000 EEPROM reading bugfix

[David Brownell]

From: David Brownell <dbrown...@users.sourceforge.net>

Make the U-Boot dm9000 driver read addresses from EEPROM just
like Linux does ... read six bytes, instead of reading twelve
bytes then discarding every one.

Using the right Ethernet address is a big win.
