Serge Semin 12d6f9f737 dma-direct: take dma-ranges/offsets into account in resource mapping 
A basic device-specific linear memory mapping was introduced back in
commit ("dma: Take into account dma_pfn_offset") as a single-valued offset
preserved in the device.dma_pfn_offset field, which was initialized for
instance by means of the "dma-ranges" DT property. Afterwards the
functionality was extended to support more than one device-specific region
defined in the device.dma_range_map list of maps. But all of these
improvements concerned a single pointer, page or sg DMA-mapping methods,
while the system resource mapping function turned to miss the
corresponding modification. Thus the dma_direct_map_resource() method now
just casts the CPU physical address to the device DMA address with no
dma-ranges-based mapping taking into account, which is obviously wrong.
Let's fix it by using the phys_to_dma_direct() method to get the
device-specific bus address from the passed memory resource for the case
of the directly mapped DMA.

Fixes: 25f1e18870 ("dma: Take into account dma_pfn_offset")
