[PATCH] dmaengine: use devm_platform_get_and_ioremap_resource()

[PATCH] dmaengine: use devm_platform_get_and_ioremap_resource()

[ye.xingchen]

From: Minghao Chi <chi.minghao@zte.com.cn>

Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.

Would you review my v3 instead?

The intention is to do this small change for all the dma drivers in a
single patch, so that we don't pollute the commit log.
