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

While at it switch the rest of the calls to read properties in
bd957x_probe() to the generic device property API as well.
With or without below addressed,

They all using parent device and you may make code neater by adding
struct device *parent = pdev->dev.parent;
This is a matter of personal preference. I prefer seeing
pdev->dev.parent - as it is more obvious (to me) what the 'pdev' is than
what 'parent' would be.
I'd use the local variable only when it shortens at least one of the
lines so that we avoid splitting it. After that being said - I'm not
going to argue over this change either if one who is improving the
driver wants to use the "helper" variable here.
