dmaengine: bestcomm: use devm_platform_get_and_ioremap_resource() to simplify code

Replace the open-coded resource lookup, request_mem_region, ioremap and
the manual iounmap/release_mem_region cleanup in probe/remove with the
managed devm_platform_get_and_ioremap_resource() helper. This removes the
now-unused error-unmap/release paths and simplifies probing.

Fix a resource size mismatch between allocating and freeing where
request_mem_region() and release_mem_region() hopefully use the same size
but is not guarenteed.
