When a device using a second or third level interrupt makes a request to
set priority, the request should be routed via the multilevel interrupt
API. Otherwise, we will configure the interrupt priority for one of the
core interrupts on the ARC controller (which is usually not what the API
caller wants)
This occurs because the ARC interrupt priority register encodes
interrupts from 0-255, so a multilevel interrupt number would simply be
masked to the lowest 8 bits (which matches the interrupt number of that
device's parent controller)
