ddr: altera: sequencer: Wrap IO_* macros
Introduce structure socfpga_sdram_io_config to wrap the IO configuration values in board file. Introduce socfpga_get_sdram_io_config() function, which returns this the structure. This is another step toward wrapping the nasty QTS generated macros in board files and reducing the pollution of the namespace.
