ARM: S5PV210: Modified files for SPI consolidation work
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. Signed-off-by: Padmavathi Venna <padma.v@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
