ARM: AM33xx+: Update ioregs to pass different values
Currently same value is programmed for all ioregs. This is not
the case for all SoC's like AM4372. So adding a structure for ioregs
and updating in all board files. And also return from config_cmd_ctrl()
and config_ddr_data() functions if data is not passed.
