Then you add dependency in wrong place. The warning you have is in:
drivers/reset/core.o

But the dependency you add is in RESET_GPIO, which is a separate driver.
While the driver indeed wants GPIO, this won't solve the original
problem. You still can have RESET_GPIO disabled and core still has the
gpiolib call to missing stub.
