core/ipmi-opal: Add interrupt-parent property for ipmi node on P9 and above.
dtc complains below warning with newer 4.2+ kernels.
dts: Warning
(interrupts_property): Missing interrupt-parent for /ibm,opal/ipmi
This fix adds interrupt-parent property under /ibm,opal/ipmi DT node on P9
and above, which allows ipmi-opal to properly use the OPAL irqchip.
