arm64 : Introduce support for ACPI _CCA object section 6.2.17 _CCA states that ARM platforms require ACPI _CCA object to be specified for DMA-cabpable devices. Therefore, this patch specifies ACPI_CCA_REQUIRED in arm64 Kconfig. In addition, to handle the case when _CCA is missing, arm64 would assign dummy_dma_ops to disable DMA capability of the device.
