How does this test distinguish between LEVEL_LOW and LEVEL_HIGH? It only
tests for level, no? So the test is interesting at best ...
There is no distinction between HIGH and LOW, RISING and FALLING, in
any revision of the GIC architecture.
Then pretending that there is a set_type() functionality is pretty daft
You still need to distinguish between level and edge when this is
programmable (which is the case for a subset of the PPIs).
