mv643xx_eth: Move ethernet register definitions into private header
Browse files Browse the repository at this point in the history 
Move the mv643xx's ethernet-related register definitions from
include/linux/mv643xx.h into drivers/net/mv643xx_eth.h, since
they aren't of any use outside the ethernet driver.
