To i.MX6, DDR3 and LPDDR2 is supported, so rename function mx6_dram_cfg to mx6_ddr3_cfg and the original mx6_dram_cfg function only is a wrapper. The new reimplemented function mx6_dram_cfg only invokes mx6_ddr3_cfg when ddr_type is for DDR3. Later we can use ddr_type to initialize MMDC for LPDDR2. Initialize ddr_type for different boards which enable SPL.
