Subject: [PATCH 2/8] ARM64: dts: marvell: armada37xx: Fix GIC maintenance
interrupt
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.
