dm: gpio: Implement GPIO reservation in the uclass

We have several GPIO drivers now and all are doing similar things to record
which GPIOs are reserved.

Move this logic into the uclass to make the drivers similar.

We retain the request()/free() methods since currently one driver does use
these for setting up the pin.
