hmm... thinking more about this, why don't you put that in the
arch/arm/plat-s3c24xx/devs.c file and then set the cfg_gpio hook in
s3c24xx_ts_set_platdata() for 2410 platforms ? 
This should be smaller change and will set it for all s3c2410 platforms
using the touchscreen once for all and "hide" it  instead of having to
set it in all machine files using the touchscreen.
