[POWERPC] 4xx: 440EPx/GRx incorrect write to DDR SDRAM errata workaround

Add a workaround for PowerPC 440EPx/GRx incorrect write to
DDR SDRAM errata. Data can be written to wrong address
in SDRAM when write pipelining enabled on plb0. We disable
it in the cpu_setup for these processors at early init.
