util/sconfig: Add LPC and ESPI buses
Picasso has an LPC and eSPI bridge on the same PCI DEVFN. They can both
be active at the same time. This adds a way to specify which devices
belong on which bus.
i.e.,
device pci 14.3 on # - D14F3 bridge
device espi 0 on
chip ec/google/chromeec
device pnp 0c09.0 on end
end
end
device lpc 0 on
end
end
BUG=b:154445472
TEST=Built trembyle and saw static.c contained the espi bus.
