ppc4xx: Big header cleanup, mostly PPC440 related
This patch starts a bit PPC4xx header cleanup. First patch mostly touches PPC440 files. A later patch will touch the PPC405 files as well. This cleanup is done by creating header files for all SoC versions and moving the SoC specific defines into these special headers. This way the common header ppc405.h and ppc440.h can be cleaned up finally. Signed-off-by: Stefan Roese <sr@denx.de>
