[PATCH] arm64: dts: socfpga: add missing interrupt-parent

[arnd@arndb.de (Arnd Bergmann)]

The PMU node has no working interrupt, as shown by this dtc warning:

arch/arm64/boot/dts/altera/socfpga_stratix10_socdk.dtb: Warning (interrupts_property): Missing interrupt-parent for /pmu

This adds an interrupt-parent property so we can correct parse
that interrupt number.

Signed-off-by: Arnd Bergmann <arnd@arndb.de>

If this looks ok, I'd apply it directly to the fixes branch
for 4.15, as the warning is one that was introduced in this
release.
