We might, even though the i2c core doesn't change the trigger type
when it retrieves the interrupt from the DT.

However, I'm a bit worried about the other probing mechanims (ACPI,
board files) that should be supported as well, and removing the
trigger type from the flags might break those. There's no board files
using it though in the tree, but I don't know about ACPI systems.

Thanks,
Maxime
