gpiolib-acpi: Move acpi_dev_add_driver_gpios() et al to consumer.h

The API, which belongs to GPIO library, is foreign to ACPI headers. Earlier
we moved out I²C out of the latter, and now it's time for
acpi_dev_add_driver_gpios() et al.

For time being the acpi_gpio_get_irq_resource() and acpi_dev_gpio_irq_get()
are left untouched as they need more thought about.

Note, it requires uninline acpi_dev_remove_driver_gpios() to keep purity of
consumer.h.
