[PATCH] S3C24xx/GPIO: Fix compile time warning

[Juergen Beisert]

Without this patch the compiler spits a warning:

arch/arm/mach-s3c24xx/gpio-s3c24x0.c: In function 'gpio_is_valid':
arch/arm/mach-s3c24xx/gpio-s3c24x0.c:176:11: warning: unused variable 'reg'
arch/arm/mach-s3c24xx/gpio-s3c24x0.c:174:11: warning: unused variable 'bit'
