[ARM] 4095/1: S3C24XX: Fix GPIO set for Bank A
GPIO bank A can only be output or a special
function, and the regs-gpio.h header has
mistakenly got this as input or output.
The mistake is carried on into the gpio.c
s3c2410_gpio_cfgpin() call which will set the
wrong value if S3C2410_GPIO_OUTPUT is passed.
