[ARM] S3C24XX: GPIO: Change to macros for GPIO numbering
Prepare to remove the large number of S3C2410_GPxn defines by moving to S3C2410_GPx(n) in arch/arm. The following perl was used to change the files: perl -pi~ -e 's/S3C2410_GP([A-Z])([0-9]+)([^_^0-9])/S3C2410_GP\1\(\2\)\3/g' Signed-off-by: Ben Dooks <ben-linux@fluff.org>
