> SRX300 firmware DT describes the CIU root and several CIB interrupt
> controllers with linux,phandle, but omits phandle.
> 
> octeon_intr_register() consumed only the latter; the controllers
> therefore never entered the interrupt controller registry, and every
> later interrupt-parent lookup for CIB, AHCI, and xHCI failed.
> 
> Thus, dev/ofw/fdt lookup code already treats phandle and linux,phandle
> as equivalent; so the Octeon interrupt layer should do the same when
> registering interrupt controllers.
