[PATCH 4/4] gpio: devres: Switch to EXPORT_SYMBOL_GPL()

[Geert Uytterhoeven]

Change all exported symbols for managed GPIO functions from
EXPORT_SYMBOL() to EXPORT_SYMBOL_GPL(), like is used for their
non-managed counterparts.

Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>
---
The only exception was gpiod_get_from_of_node(), as everything in
drivers/gpio/gpiolib-of.c used EXPORT_SYMBOL(), until the previous
patch.
