[netdrvr] au1000_eth: Spinlock initialisation fix
Seems like the spinlock for the AU1x00 ethernet device is initialised too late, as it is already used in enable_mac(), which is called via mii_probe() before the init takes place. The attached patch is working here for a Linux Au1100 2.6.22.6 kernel, and as far as I checked should also be applicable to the current head (just line numbers differ).
