GPIO hogs are handled separately in three places: for OF, ACPI and

A lot of that code is actually redundant and - except for some special
handling of OF nodes - can be unified in one place.

This series moves hogging into GPIO core and bases it on fwnode API
(with a single helper from OF to translate devicetree properties into
lookup flags), converts the two remaining users of machine hogs to using
software node approach and removes machine hog support entirely. In
addition, there's a patch extending the configurability of gpio-sim now
that it uses software nodes for hogs.

For merging: I think this should go through the GPIO tree with an Ack
from OMAP1 maintainers.

Even with the new feature for gpio-sim, this series still removes twice
the number of lines, it adds.

Lovely! This was in my TODO list somewhere deep, but I never started it for
real (had some very very initial patches)

(Maybe I will have time to test it later on, I need to check if there is a use
of them on Intel Galileo Gen1 platform).
