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
if ISL/PSL is 80.
TESTED=tried on a server with Intel Emmitsburg PCH, flash update
was successful. This server, however, does not have flash chip
installed, it instead has em100 emulator connected.
