ppc4xx: Reset and relock memory DLL after SDRAM_CLKTR change
After changing SDRAM_CLKTR phase value rerun the memory preload
initialization sequence (INITPLR) to reset and relock the memory
DLL. Changing the SDRAM_CLKTR memory clock phase coarse timing
adjustment effects the phase relationship of the internal, to the
PPC chip, and external, to the PPC chip, versions of MEMCLK_OUT.
