How do you suggest to get a reasonable display name out of
the device tree?  The recommended human-readable name for
interrupt controller nodes is "interrupt-controller"...
You cannot use "device_type" either, and using "compatible"
requires selecting one of its string entries, and likely
using a lookup table after that, too.
