[PATCH v2 0/4] Fix handling of GPIO keys and LEDs on geode

This series deal with breakage on geode caused by a recent conversion of
the board to use static device properties for configuring GPIO-connected
keys and LEDs. The issue was that PROPERTY_ENTRY_GPIO() would create a
temporary structure on stack for GPIO properties which would later be
discarded.

The first change patches the behavior using existing in kernel APIs so
that the bug can easily be fixed in stable kernels, and the other 3
improve the API and add safety checks.
