imx: mx6: ddr init MMDC according to ddr_type
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.
