gpio: Add a valid_mask getter
The valid_mask member of the struct gpio_chip is unconditionally written
by the GPIO core at driver registration. It shouldn't be directly
populated by drivers. This can be prevented by moving it from the struct
gpio_chip to struct gpio_device, which is internal to the GPIO core.
As a preparatory step, provide a getter function which can be used by
those drivers which need the valid_mask information.
