gpiolib: No need to call gpiochip_remove_pin_ranges() twice

gpiolib: No need to call gpiochip_remove_pin_ranges() twice

commit 2f4133bb5f14f49a99acf0cc55b84996dbfb4dff upstream.

of_gpiochip_add(), when fails, calls gpiochip_remove_pin_ranges().

ADD:
  gpiochip_add_data_with_key() ->
    of_gpiochip_add() -> (ERROR path)
      gpiochip_remove_pin_ranges()

At the same time of_gpiochip_remove() calls exactly the above mentioned
function unconditionally and so does gpiochip_remove().

REMOVE:
  gpiochip_remove() ->
    gpiochip_remove_pin_ranges()
    of_gpiochip_remove() ->
      gpiochip_remove_pin_ranges()

Since gpiochip_remove() calls gpiochip_remove_pin_ranges() unconditionally,
we have duplicate call to the same function when it's not necessary.

Move gpiochip_remove_pin_ranges() from of_gpiochip_add() to gpiochip_add()
to avoid duplicate calls and be consistent with the explicit call in
gpiochip_remove().
