gpio: Pass mask and size with the init_valid_mask()
It is more helpful for drivers to have the affected fields directly available when we use the callback to set up the valid mask. Change this and switch over the only user (MSM) to use the passed parameters. If we do this we can also move the mask out of publicly visible struct fields.
