Currently, SMMU support is forced to be enabled unconditionally in the probe function. This can lead to errors on platforms where the audio memory device does not have an IOMMU assigned in the device tree. Update the driver to check for the existence of the 'iommus' property in the device tree node. SMMU support is now enabled only if this property is present. Additionally, add a fallback to disable SMMU support if the SMMU SID parsing fails, ensuring the driver does not attempt to use an invalid SID configuration.
