Subject: [PATCH 06/12] drm/sprd: move to devm_platform_ioremap_resource()
 usage

Replace platform_get_resource + devm_ioremap
with just devm_platform_ioremap_resource()

Used Coccinelle to do this change. SmPl patch:
@rule_2@
identifier res;
expression ioremap;
identifier pdev;
@@
-struct resource *res;
...
-res = platform_get_resource(pdev,...);
<...
-if (!res) {
-...
-}
...>
-ioremap = devm_ioremap(...);
+ioremap = devm_platform_ioremap_resource(pdev,0);
