Subject: [PATCH] ata: Make use of the helper function devm_platform_ioremap_resource()

From: Lv Ruyi <lv.ruyi@....com.cn>

Use the devm_platform_ioremap_resource() helper instead of calling
platform_get_resource() and devm_ioremap_resource() separately.Make the
code simpler without functional changes.
