gpio: of: Make of_gpio_simple_xlate() private

Browse source 
Since commit 9a95e8d25a ("gpio: remove etraxfs driver"), there are
no more users of of_gpio_simple_xlate() outside gpiolib-of.c.
All GPIO drivers that need it now rely on of_gpiochip_add() setting it
up as the default translate function.
