[PATCH V3 3/6] ARM: S5PC100: Modified files for SPI consolidation work

[Padmavathi Venna]

As SPI platform devices are consolidated to plat-samsung, some
corresponding changes are required in the respective machine folder.
Added SPI Setup file for GPIO configurations and platform data
initialization.
