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.
