Define two structure mx6sx_iomux_ddr_regs and mx6sx_iomux_grp_regs. Add a new function mx6sx_dram_iocfg to configure dram io. Since mx6sx only have one channel mmdc0, define a new empty macro MMDC1 to replace mmdc1->entry=value for mx6sx. And to other mx6 soc, MMDC1 effects as "mmdc1->entry=value".
