Add support for Intel Emmitsburg PCH

This patch does the following:
- Add PCIe ID for Intel Emmitsburg PCH
- Based on ICH descriptor content, choose
  CHIPSET_C620_SERIES_LEWISBURG. Although EBG only uses 80 for its PSL
  value, LBG on Purley and Whitley use 139. So to cover both cases the
  latter is used.

TESTED=tried on different servers with Intel Emmitsburg PCH, flash
update was successful. Some servers have flash chip installed, another
one has em100 emulator connected.
