	1. Define two structures mx6ul_iomux_ddr_regs and mx6ul_iomux_grp_regs. 2. Add a new function mx6ul_dram_iocfg to configure dram io. 3. Refactor MMDC1 macro, discard "#ifdef CONFIG_MX6SX". Since only mmdc0 channel exists on i.MX6SX/UL, redefine MMDC1 macro support runtime check, but not hardcoding #ifdef macros. 4. Introduce mx6ul-ddr.h, which includes the register address for DRAM IO configuration. Signed-off-by: Peng Fan <Peng.Fan@freescale.com>
