Propagate error code of gpiochip_add() up the call chain. This won't
do any meaningful cleanup, but at least it will make problems
noticable.

Since commit 37e6bee7e5 ("gpiolib: Add support for GPIO "hog" nodes")
barebox can handle hog-gpios. To work correctly the pinctrl driver
must be initialised first. Reorder all core_initcall's so the pinctrl
driver can be called first.
find drivers/gpio/ -type f -name gpio-*.c -exec sed -i \
's/core_initcall/postcore_initcall/' "{}" +;
