ACPI: add support for CSRT table
Core System Resources Table (CSRT) is a proprietary ACPI table that contains resources for certain devices that are not found in the DSDT table. Typically a shared DMA controller might be found here. This patch adds support for this table. We go through all entries in the table and make platform devices of them. The resources from the table are passed with the platform device. There is one special resource in the table and it is the DMA request line base and number of request lines. This information might be needed by the DMA controller driver as it needs to map the ACPI DMA request line number to the actual request line understood by the hardware. This range is passed as IORESOURCE_DMA resource.
