[PATCH v5 1/4] base/platform: Only insert MEM and IO resources

[Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com>]

platform_device_del only checks the type of the resource in order to
call release_resource.

On the other hand, platform_device_add calls insert_resource for any
resource that has a parent.

Make both code branches balanced.
