ppc4xx: Enable 405EP PCI arbiter per default on all boards
In an attmemt to clean up the 4xx start.S file, I removed the enabling of the internal 405EP PCI arbiter. This is needed for multiple other 405EP platforms, like most of the esd 405EP. Now the internal PCI arbiter is enabled again per default as it has been before. Signed-off-by: Stefan Roese <sr@denx.de> Acked-by: Matthias Fuchs <matthias.fuchs@esd-electronics.com>
