Subject: [PATCH v3 2/7] dt-bindings: hypervisor: Add MediaTek GenieZone hypervisor

From: "Yingshiuan Pan" <yingshiuan.pan@...iatek.com>

Add documentation for GenieZone(gzvm) node. This node informs gzvm
driver to start probing if geniezone hypervisor is available and
able to do virtual machine operations.

+description:
+  This interface is designed for integrating GenieZone hypervisor into Android
+  Virtualization Framework(AVF) along with Crosvm as a VMM.
+  It acts like a wrapper for every hypercall to GenieZone hypervisor in
+  order to control guest VM lifecycles and virtual interrupt injections.
