Linus Walleij 545ebd9a9b gpio: drop lock before reading GPIO direction ...

When adding the gpiochip, the GPIO HW drivers' callback get_direction()
could get called in atomic context. Some of the GPIO HW drivers may
sleep when accessing the register.

Move the lock before initializing the descriptors.
