ppc4xx: Big cleanup of PPC4xx defines
This patch cleans up multiple issues of the 4xx register (mostly DCR, SDR, CPR, etc) definitions: - Change lower case defines to upper case (plb4_acr -> PLB4_ACR) - Change the defines to better match the names from the user's manuals (e.g. cprpllc -> CPR0_PLLC) - Removal of some unused defines Please test this patch intensive on your PPC4xx platform. Even though I tried not to break anything and tested successfully on multiple 4xx AMCC platforms, testing on custom platforms is recommended. Signed-off-by: Stefan Roese <sr@denx.de>
