Request direct mapping for modem on platforms which don't have TrustZone (which programs the modem SIDs) to prevent the following global faults seen on Cheza/Trogdor:
arm-smmu 15000000.iommu: Unexpected global fault, this could be serious arm-smmu 15000000.iommu: GFSR 0x80000002, GFSYNR0 0x00000000, GFSYNR1 0x00000781, GFSYNR2 0x00000000
