leds: leds-gpio - fix a section mismatch

WARNING: drivers/leds/leds-gpio.o(.text+0x153): Section mismatch in reference from the function gpio_led_probe() to the function .devinit.text:create_gpio_led()

The function gpio_led_probe() references the function __devinit
create_gpio_led().  This is often because gpio_led_probe lacks a __devinit
annotation or the annotation of create_gpio_led is wrong.
