soc: qcom: Add hypervisor abstraction driver 



This new driver is meant to be a cross-platform abstraction
layer for utilizing the underlying hypervisor system.
This API can be accessed from both user and kernel sides.
The intended users of this are the multimedia drivers who want
to communicate with the host OS to use the multimedia hardware.

QVM Guest Shared Memory



guest_shm is a device that enables linux as a guest operating system

to allocate shared memory between virtual machines and send notifications

of updates to other virtual machines.



Required properties:

- compatible:		Must be "qvm,guest_shm".

- interrupt-parent:	Parent interrupt controller.

- interrupts:		Should contain QVM interrupt.

- reg:			Physical address of the guest factory and length.



Example:

	qvm,guest_shm {

		compatible = "qvm,guest_shm";

		interrupt-parent = <&gic>;

		interrupts = <6 4>;

		reg = <0x1c050000 0x1000>;

	};
