[PATCH] spi_s3c24xx.c: warning fix

The set_cs field of struct s3c24xx_spi is declared as returning a int but
the value returned but set_cs is never fixed.  Moreover, the default
function for set_cs and the set_cs defintion in the platform data are
returning void.

I'm proposing to change the prototype to void (*set_cs)(...). By doing
this, I'm also fixing 2 build warnings:

  drivers/spi/spi_s3c24xx.c: In function 's3c24xx_spi_probe':
  drivers/spi/spi_s3c24xx.c:330: warning: assignment from incompatible pointer type
  drivers/spi/spi_s3c24xx.c:335: warning: assignment from incompatible pointer type
