Every Qcom Adreno GPU has an embedded SMMU for its own use. These
devices depend on unique features such as split pagetables,
different stall/halt requirements and other settings. Identify them
with a compatible string so that they can be identified in the
arm-smmu implementation specific code.
Si
Add domain attribute DOMAIN_ATTR_PGTABLE_CFG. This will be used by
arm-smmu to share the current pagetable configuration with the
leaf driver and to allow the leaf driver to set up a new pagetable
configuration under certain circumstances.

Add support for allocating private address space instances. Targets that
support per-context pagetables should implement their own function to
allocate private address spaces.
The default will return a pointer to the global address space.
