dma-mapping: fix handling of dma-ranges for reserved memory (again) [ Upstream commit a445e940ea686fc60475564009821010eb213be3 ] Daniele reported that issue previously fixed in c41f9ea998f3 ("drivers: dma-coherent: Account dma_pfn_offset when used with device tree") reappear shortly after 43fc509c3efb ("dma-coherent: introduce interface for default DMA pool") where fix was accidentally dropped. Lets put fix back in place and respect dma-ranges for reserved memory.
