platform: pass singleton instance to nm_platform_setup()

We have two hooks to modify setup of the platform singleton:
nm_linux_platform_setup() and the virtual setup() function.

On the other hand, nm_platform_setup() limits us by accepting
only a GType, instead of a prepeared platform instance.
Make the nm_platform_setup() method more flexible, so that we can
later drop the setup() hook.
