Looks like this patch causes a regression where GPIOs on I2C will
no longer return -EPROBE_DEFER but seem to return -ENOENT instead.

This breaks drivers using things like devm_gpiod_get_index()
on a GPIO that's on a I2C bus not probed yet.

Reverting commit dd34c37aa3e (gpio: of: Allow -gpio suffix for
property names) fixes things.

Regards,

Tony
