I've been using patches that change gpio and i2c initialization to module_init
for some time now. However, I still see some non-DT boards using the GPIO API
in early functions such as .init_machine.
Only when these boards get converted and the legacy support is dropped, we'll
be able to move all the drivers to module_init.
