Timur Tabi 1704eb50f3 Revert "gpio: set up initial state from .get_direction()" 
[ Upstream commit 1ca2a92b2a ]

This reverts commit 72d3200061.

We cannot blindly query the direction of all GPIOs when the pins are
first registered.  The get_direction callback normally triggers a
read/write to hardware, but we shouldn't be touching the hardware for
an individual GPIO until after it's been properly claimed.
