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

Fri Nov 4 08:43:51 EDT 2011
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.
SPI platform specific data is initialized in the corresponding
machine file.
