When SMMU is enable this will cause address truncation and translation faults. Hence introducing "altr,agilex5-axi-dma" to enable platform specific configuration to configure the dma addressable bit mask. Add a fallback capability for the compatible property to allow driver to probe and initialize with a newly added compatible string without requiring additional entry in the driver.
