Subject: [PATCH v1 09/11] regulator: bd9576: switch to using devm_fwnode_gpiod_get()

I would like to stop exporting OF-specific devm_gpiod_get_from_of_node()
so that gpiolib can be cleaned a bit, so let's switch to the generic
fwnode property API.

While at it switch the rest of the calls to read properties in
bd957x_probe() to the generic device property API as well.
