driver/ddr: Restruct driver to allow standalone memory space
U-boot has been initializing DDR for the main memory. The presumption is the memory stays as a big continuous block, either linear or interleaved. This change is to support putting some DDR controllers to separated space without counting into main memory. The standalone memory controller could use different number of DIMM slots.
