[PATCH V3 2/6] ARM: S3C64XX: 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.
Setup files are added for SPI GPIO configurations and platform data
initialization.
