gpio: restore missing legacy devicetree direction flag

Browse source 
GPIO_DIR_OUT is deprecated but allowed in devicetree bindings because
some in-tree bindings provided it in the past.  GPIO_DIR_IN was the
former explicit way of representing the default direction.  Put it
back so symmetry is maintained.
