Anton Vorontsov afd8e39919 uli526x: initialize the hardware prior to requesting interrupts
The firmware on MPC8610HPCD boards enables ULI ethernet and leaves it
in some funky state before booting Linux. For drivers, it's always good
idea to (re)initialize the hardware prior to requesting interrupts.

This patch fixes the following oops:
