drivers/gpio/nomadik: move dummy nmk_gpio_dbg_show_one() to header
When `CONFIG_DEBUG_FS` is disabled, nmk_gpio_dbg_show_one() is an empty dummy function; this however triggers a `-Wmissing-prototypes` warning and later a linker error because the function is also used by drivers/pinctrl/nomadik/pinctrl-nomadik.c, therefore it needs to be non-static. To allow both sources to access this dummy function, this patch moves it to the header, adding the `#ifdef CONFIG_DEBUG_FS` there as well.
