ARM: S3C2440: fix boot failure introduced by recent changes in gpiolib

Recent changes in s3c gpio break mini2440 board and may be others.
The problem is that mach-mini2440.c: mini2440_init()
(where we call s3c_gpio_setpull()) is called before s3c2440.c: s3c2440_init()
(where we initialize s3c24xx_gpiocfg_default.set_pull function pointer).
This causes dereferencing of NULL pointer at boot time and a kernel panic.
