[Duncan Laurie (Code Review)]

Hello build bot (Jenkins), Furquan Shaikh, Patrick Georgi, Martin Roth, Tim Wawrzynczak, Angel Pons, Aaron Durbin,

I'd like you to reexamine a change. Please visit

sconfig: Allow chipset to provide a base devicetree

This change extends the devicetree override one more layer and allows the
chipset to provide the base devicetree.  This allows the chipset to assign
alias names to devices as well as set default register values.  This works
for both the baseboard devicetree.cb as well as variant overridetree.cb.

chipset.cb:
device pci 15.0 alias i2c0 off end

devicetree.cb:
device ref i2c0 on end
