It's hard for occasional GPIO code reader/writer to know if values 0/1
equal to IN or OUT. Use defined GPIO_LINE_DIRECTION_IN and
GPIO_LINE_DIRECTION_OUT to help them out.

NOTE: This commit also changes the return value for direction get
to equal 1 for direction INPUT. Prior this commit the driver returned
non standard value BIT(23).
