Add an interrupt specification to the bindings to support the wait-queue
feature.

The interrupt property for scm firmware from a binding perspective is
completely optional i.e. not all tz fw running in the wild on sm8450
devices support this feature. The bootloader does the interrupt property
addition on sm8450 devices with wait-queue support.

You still miss here constraints... nothing improved. Just look at other
properties in this file.
