dma: replace devm_request_and_ioremap by devm_ioremap_resource
Use devm_ioremap_resource instead of devm_request_and_ioremap. This was done using the semantic patch scripts/coccinelle/api/devm_ioremap_resource.cocci The relevant call to platform_get_resource was manually moved down to the call to devm_ioremap_resource.
