There can be different types of interrupt controllers in a system and some drivers may need to distinguish between these. In general this can be handled using the device tree by adding the interrupt information to device nodes. However on x86 devices we have interrupt controllers which are not tied to any particular device and not really used in U-Boot. These still need to be inited, so a convenient method is to give each controller a type and allow a particular controller type to be probed. Add support for this in sandbox along with a test.
