Instead of asymmetrical checks for the firmware use is_*_node()
calls. With that, drop now local wrappers against

I have to partially agree with Jarkko here, the patch splitting
of this series is a bit too exotic. Series need to be understood
by reading them forward, not backward.

Oversplitting sometimes might even reduce readability and
"reviewability" (can I say so?). And this function, in seven
patches, has been added, moved and removed, and I had to read the
series twice :)

Anyway, I won't ask you to refactor the whole series, I
understand your logic.
