[PATCHv4 4/6] iommu/arm-smmu-qcom: Request direct mapping for modem device

[Sai Prakash Ranjan]

From: Sibi Sankar <sibis@xxxxxxxxxxxxxx>

The Q6 modem sub-system has direct access to DDR through memnoc.
Also SMMU is not expected to provide access control/translation
for these SIDs (sandboxing of the modem is achieved through XPUs
engaged using SMC calls). So request direct mapping for modem on
platforms which don't have TrustZone.
