[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.
