[PATCH 40/58] move s3c241xfb's probe function to .devinit.text

Pointers to s3c2410fb_probe and s3c2412fb_probe are passed to the core
via platform_driver_register and so the functions must not disappear
when the .init sections are discarded. Otherwise (if also having
HOTPLUG=y) unbinding and binding a device to one of the drivers via
sysfs will result in an oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.
