ARM: SAMSUNG: Modify s3c64xx_spi{0|1|2}_set_platdata function

Browse Source 
With the spi controller hardware configuration moved into the driver data, there
are no more default hardware configuration data that is passed through platform
data. Accordingly, the s3c64xx_spi{0|1|2}_set_platdata functions are adapted to
these changes.
