[PATCH 13/14] drm/vc4: move to devm_platform_ioremap_resource() usage

[Anusha Srivatsa]

Replace platform_get_resource_byname + devm_ioremap_resource
with just devm_platform_ioremap_resource()

Used Coccinelle to do this change. SmPl patch:
//rule s/(devm_)platform_get_resource_byname +
//(devm_)ioremap/devm_platform_ioremap_resource.
