Add DDR3 support into the MPC8xxx DDR driver.
To avoid confusion, the function set_ddr_sdram_mode is renamed
set_ddr2_sdram_mode.
Checking for errors is simplified in the DDR2 DIMM parameters
computation to be consistent with DDR3.
This code is derived from the files found in directory drivers/ddr/fsl
from U-Boot version git-be937b5.

Definitions and structures have been added to record DIMM parameters
and configure memory options.
The code is based on the equivalent files in the directory
arch/powerpc/include/asm from U-boot version git-a71d45d.
