of: irq: Ignore disabled intc's when searching map 

When searching the interrupt map, if a matched parent is disabled, just
ignore it and move on with the search.

This allows for specifying connection of a single device IRQ to
multiple interrupt controllers via the interrupt map schema. This change
allows for selection of the active interrupt controller via the already
existing status = "disabled" mechanism.
