mfd: arizona: Update reset pin to use GPIOD
Now GPIOD has support for both pdata systems and for non-standard DT bindings the Arizona reset GPIO can be converted to use it. Worth noting gpiod_set_raw_value_cansleep is used to match the behaviour of the old GPIOs. This is because the part is fairly widely used and it is unknown how many DTs are correctly setting active low through device tree, so to avoid breaking any existing users it is best to match the previous behaviour.
