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.
