The modem remote processor has two modes of access to the DDR, a direct mode and through a SMMU which requires direct mapping. The configuration of the modem SIDs is handled in TrustZone. On platforms where TrustZone is absent this needs to be explicitly done from kernel. Add compatibles for modem to opt in for direct mapping on such platforms.
