[PATCH v7 02/16] dt-bindings: hypervisor: Add MediaTek GenieZone hypervisor

[Yi-De Wu]

From: "Yingshiuan Pan" <yingshiuan.pan at mediatek.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.

[Detail]
The debate of using dt or not remains intact, and gentle ping seems not
working on this issue. We'll keep this patch for further discussion and
move forward in order to rebase based on the latest rc release. For
previous discussion, please kindly refer to the following link.

+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.
