soc: qcom: add audio apr and ion virtualization support

Add support for virtualized APR and ION frontend driver
for audio.
Virtualized APR frontend driver resides in guest VM and
supports all legacy APR APIs. It will rely on MSM_HAB
to communicate with APR backend driver, which resides in
physical VM, where legacy SMD is utilized for communication
between APPS and ADSP.
Virtualized ION driver currently is designed to extract
physical memory through hypervisor abstracted ion layer,
which can be shared between APPS and ADSP directly.
