Linus Walleij 2145ba3740 gpio: mmio: Add flag for calling pinctrl back-end ...

It turns out that with this flag we can switch over an entire
driver to use gpio-mmio instead of a bunch of custom code,
also providing get/set_multiple() to it in the process, so it
seems like a reasonable feature to add.

The generic pin control backend requires us to call the
gpiochip_generic_request(), gpiochip_generic_free(),
pinctrl_gpio_direction_output() and pinctrl_gpio_direction_input()
callbacks, so if the new flag for a pin control back-end
is set, we make sure these functions get called as
expected.
