ppc4xx: Cleanup CPCI405 board code
This patch cleans up CPCI405 board support: - wrap long lines - unification of spaces in function calls - remove dead code Use correct io accessors on peripherals. Signed-off-by: Matthias Fuchs <matthias.fuchs@esd-electronics.com> Signed-off-by: Stefan Roese <sr@denx.de>
