I don't buy the argument that we can't add one thing because if we
added a hundred that would be too much.  You could add
of_get_gpio_flags, get that upstream, then get the driver patches
upstream, then submit a patch to remove of_get_gpio.  Alternatively
you could make of_get_gpio a macro or inline function in of_gpio.h.

If you really want to change everything in one hit you'll have to get
acks + agreement for the change to go upstream via my tree from all
the relevant driver maintainers first.  I don't see any particular
advantage to doing it that way, though.
