net: macb: fix network configuration error when using gmac with non-Gbit PHY

If the ethernet controller is detected as GMAC, the driver silently
assumes, that the connected PHY is also 1000Mbit capable and reads the
probably non-existant MII_STAT1000 register. This may lead to falsely
assuming a 1000Mbit link.
