Subject: [PATCH] qcacld-3.0: Enable SMMU S1 unmap config flag for Lahaina

IOVA address returned as part of pld_smmu_map for IPA
rx ready doorbell register exceeds the IOVA range
configured in FW by Host. This is because smmu unmap
support is not enabled and due to IOVA range validation
issue in cnss SMMU map API.

Fix is to enable SMMU S1 unmap config flag to enable
SMMU unmap as part of IPA cleanup.
