    mv643xx_eth: Move ethernet register definitions into private header
    
    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.

arch/powerpc/platforms/chrp/pegasos_eth.c made use of a 3 defines there.

mcgrof@...o:~/devel/wireless-2.6$ git-describe 

v2.6.24-rc1-138-g0119130

This patch fixes this by internalizing 3 defines onto pegasos which are
simply no longer available elsewhere. Without this your compile will fail
whenever you enable 'Common Hardware Reference Platform (CHRP) based machines',
(CONFIG_PPC_CHRP) as the Makefile for chrp adds it always:

obj-y                           += setup.o time.o pegasos_eth.o pci.o

If these defines are platform specific then they should later just be added 
back to include/linux/mv643xx.h.

Compile error:
