Fix the wrong mapping between the DDR I/O control registers on AM33XX
SoCs and the software representation in the SPL code.
The most recent public TRM defines the following DDR I/O control registers
offsets:
* ddr_cmd0_ioctrl : offset 0x44E11404
* ddr_cmd1_ioctrl : offset 0x44E11408
* ddr_cmd2_ioctrl : offset 0x44E1140C
* ddr_data0_ioctrl: offset 0x44E11440
* ddr_data1_ioctrl: offset 0x44E11444
While the struct ddr_cmdtctrl has also some reserved bits in the beginning.
The struct is mapped to the address 0x44E11404. As a result "cm0ioctl" points
to the ddr_cmd1_ioctrl register, "cm1ioctl" to the ddr_cmd2_ioctrl and etc.
Registers ddr_cmd0_ioctrl and ddr_data0_ioctrl are never configured because
of this mapping mismatch.
