[ARM] 3033/1: S3C2410 - add generic gpio_cfgpin options
Patch from Ben Dooks Add generic values for the parameters to the s3c2410_gpio_cfgpin() function, so that a caller does not need to know the exact constant for the specified pin. This is very useful for the case where a driver is passed a gpio pin number and needs to reconfigure the pin's function.
