I haven't had time to look into this yet, in part because I just don't
know how well to trust my h/w, but to get SMC1 console working (RPX
Lite) I need to enable both SCC1 and SMC1.  For your board, I would
recommend enabling all of the consoles.

And in case others were wondering, the old driver has a different set of
issues, at least on my hw, it doesn't see input (and/or it causes a
livelock at boot, I haven't tried again in a while).
