pinctrl: exynos: don't mark probing functions as __init

Functions called from a driver probe() method must not be
marked __init, because they may get called after the
init phase is done, when the device shows up late, or
because of deferred probing.

Without this patch, building exynos_defconfig results in
multiple warnings like:

WARNING: drivers/pinctrl/built-in.o(.text+0x51bc): Section mismatch in reference from the function exynos5440_pinctrl_probe() to the function .init.text:exynos5440_gpiolib_register()
The function exynos5440_pinctrl_probe() references
the function __init exynos5440_gpiolib_register().
This is often because exynos5440_pinctrl_probe lacks a __init
annotation or the annotation of exynos5440_gpiolib_register is wrong.
