ARM64: dts: marvell: armada-37xx: Fix GIC maintenance interrupt

BugLink: http://bugs.launchpad.net/bugs/1717549
commit 95696d292e204073433ed2ef3ff4d3d8f42a8248 upstream.

The GIC-500 integrated in the Armada-37xx SoCs is compliant with
the GICv3 architecture, and thus provides a maintenance interrupt
that is required for hypervisors to function correctly.

With the interrupt provided in the DT, KVM now works as it should.
Tested on an Espressobin system.
