ddr: altera: sequencer: Wrap IO_* macros

Browse Source 
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.
