[ARM] S3C24XX: GPIO: Remove s3c2410_gpio_irq2pin() call
Remove the s3c2410_gpio_irq2pin() function as it is not being used in any in kernel driver and the function is probably not being used anywhere else. This is also part of the effort to remove any of the s3c24xx gpio specific code that cannot be recreated by using the gpiolib framework now in the kernel.
