sundance: Really read addr 0
Make phy 0 actually be read, as it is not being right now as we have:
int mii_status = mdio_read(dev, phy, MII_BMSR);
int phyx = phy & 0x1f;
When we should have instead:
int phyx = phy & 0x1f;
int mii_status = mdio_read(dev, phyx, MII_BMSR);
so that when phy, in the end of the (phy = 1; phy <= 32...) loop gets
to 32 phyx gets to 0, i.e. we were reading at 32, when the intended
read was for 0.
