If the gpio DT node has the gpio-ranges property, the range will be
added by the gpio core and doesn't need to be added by the pinctrl
driver.

By having the gpio-ranges property, we have an explicit dependency from
the gpio node to the pinctrl node and we can stop using the deprecated
pinctrl_add_gpio_range() function.

Note that when the GPIO device gets probed before the associated
princtrl device, the gpio core actually won't register the gpio range.
Thus, this patch is only safe to be merged after we have in place a way
to assure that gpio devices are probed after their associated pinctrl
devices (such as ordered probing).

This doesn't look like it would hurt, but need Stephen's opinion
on it, and I think he's on vacation. Would check with next-in-line
Tegra maintainer, Thierry/Alexandre?
