Subject: [PATCH] gpio: remove duplicated function definition

when building without CONFIG_PINCTRL:

In file included from drivers/hwmon/pmbus/ucd9000.c:19:0:
./include/linux/gpio/driver.h:576:1: error: redefinition of gpiochip_add_pin_range
 gpiochip_add_pin_range(struct gpio_chip *chip, const char *pinctl_name,
 ^~~~~~~~~~~~~~~~~~~~~~
In file included from drivers/hwmon/pmbus/ucd9000.c:18:0:
./include/linux/gpio.h:245:1: note: previous definition of gpiochip_add_pin_range was here

 ^~~~~~~~~~~~~~~~~~~~~~
