[PATCH] Sun HME: enable and map PCI ROM properly
This ports the Sun GEM ROM mapping/enable fixes it sunhme (which used
the same PCI ROM mapping code).
Without this, I get NULL MAC addresses for all 4 ports (it's a SUN QFE).
With it, I get the correct addresses (the ones printed on the label on
the card).
