gpio: aggregator: Fix calling into sleeping GPIO controllers

If the parent GPIO controller is a sleeping controller (e.g. a GPIO
controller connected to I2C), getting or setting a GPIO triggers a
might_sleep() warning.  This happens because the GPIO Aggregator takes
the can_sleep flag into account only for its internal locking, not for
calling into the parent GPIO controller.

Fix this by using the gpiod_[gs]et*_cansleep() APIs when calling into a
sleeping GPIO controller.
