soc: qcom: add SMMU support for virtualized audio ION driver

Update the virtualized audio ION driver to add SMMU support.
The virtualized audio ION driver will provide the ION memory
allocated from the guest VM to the physical VM to perform SMMU
mapping.

The virtualized audio ION driver will receive SMMU mapped
device address from physical VM and provide the device address
to its clients. Upon its client frees the memory, the virtualized
audio ION driver will request the physical VM to perform SMMU
un-mapping.
