The PMU remains mostly the same, the main work is the hypertransport bits
I think or at least mimmic them enough using PCI, but we'll see.

I'm adding one GPIO for the PMU, the rest is less important. We can
probably get a pretty good model without any i2c. It's used for things
like clocks control, some sound chips, fans, and so .. anyway, we'll
see.
