Add a Gunyah protected guest driver. A Gunyah protected guest needs to be hypervisor-aware to relinquish pages to the host/owner for virtio-balloon. In the Android Virtualization Framework model, the host/owner VM, not the hypervisor, owns the virtio devices. The hypervisor is unaware about the virtio device and thus the guest needs to inform the hypervisor that the host can access guest-private memory.

Protected guests running under the Gunyah hypervisor
|
|
are isolated from the host and must issue hypercalls to enable
|
|
interaction with virtual devices. This driver implements
|
|
support for probing and issuing these hypercalls.

If unsure, say 'N'.
