During the locking rework in GPIOLIB, we omitted one important use-case, namely: setting and getting values for GPIO descriptor arrays with array_info present.

This patch does two things: first it makes struct gpio_array store the address of the underlying GPIO device and not chip. Next: it protects the chip with SRCU from removal in gpiod_get_array_value_complex() and gpiod_set_array_value_complex().

Applied, thanks!
