Hi Arnd

This pattern is used in other places, e.g. when creating the
clocks. The macro MV643XX_ETH_NAME is also used when creating the
platform data, and in the driver itself. 

Are you suggested we replace this with "mv643xx_eth.0"? Or is adding
the macro

#define MV643XX_ETH_NAME0 "mv643xx_eth.0" 

in include/linux/mv643xx_eth.h O.K, since grep will find it, and
induce the grep'er to perform a second grep on the macro?
