util/sconfig: Add LPC and ESPI buses

Browse Source 
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.
