gpio: introduce a header for symbols shared by suppliers and consumers 



GPIO_LINE_DIRECTION_IN/OUT definitions are used both in supplier (GPIO
controller drivers) as well as consumer code. In order to not force the
consumers to include gpio/driver.h or - even worse - to redefine these
values, create a new header file - gpio/defs.h - and move them over
there. Include this header from both gpio/consumer.h and gpio/driver.h.
