This series allows DRM, Modem devices to set a default
identity mapping in qcom smmu implementation.

Patch 1 is cleanup to support other SoCs to call into
QCOM specific implementation.
Patch 2 sets the default identity domain for DRM devices.
Patch 3 implements def_domain_type callback for arm-smmu.
Patch 4 sets the default identity domain for modem device.
Patch 5-6 adds the iommus property for mss pil.

This is based on Joerg's tree:
- https://git.kernel.org/pub/scm/linux/kernel/git/joro/linux.git/log/?h=iommu-probe-device-v2

v4:
* Updated commit msg for mss pil requesting direct mapping

v3:
* Use arm_smmu_master_cfg to get impl instead of long way as per Robin.
* Use def_domain_type name for the callback in arm_smmu_imp as per Robin
