[RESEND PATCH 01/62] gpio: Add definition for GPIO direction

At least for me it is difficult to remember the meaning of GPIO
direction values. Define GPIO_LINE_DIRECTION_IN and
GPIO_LINE_DIRECTION_OUT so that occasional GPIO contributors would
not need to always check the meaning of hard coded values 1 and 0.

Sorry for folks. I do resend this single patch as this was intended
to be sent for _all_ reviewers. I accidentally did originally send
this only to those the get_maintainer.py listed for this patch.
