ARM: 6177/1: nomadik-gpio: fix "ignoring return value" warning

Browse Source 
arch/arm/plat-nomadik/gpio.c: In function 'nmk_gpio_remove':
arch/arm/plat-nomadik/gpio.c:630: warning: ignoring return value of 'gpiochip_remove', declared with attribute warn_unused_result

Because this function is marked __exit and this code can't be built as a
module, this function is never used.  So just remove it, fixing the
warning in the process.
