This patch update of_dma_configure() API to calculate the masks (dma_mask and coherent_dma_mask) based on the dma-range values set in DT for the device. Also limit the mask to lower of the default mask and mask calculated.

I had applied it to my local branch, but not pushed it to kernel.org. I applied it along with the "get DMA configuration from parent device" series to pci/murali-v8 and pushed it for build testing. Bjorn
