[flashrom-gerrit] Change in flashrom[staging]: chispet_enable: Add support for C620-series Lewisburg PCH

[David Hendricks (Code Review)]

Hello Paul Menzel, build bot (Jenkins), Nico Huber,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#2).

Change subject: chispet_enable: Add support for C620-series Lewisburg PCH

chispet_enable: Add support for C620-series Lewisburg PCH

This adds PCI IDs for C620-series PCHs and adds
CHIPSET_C620_SERIES_LEWISBURG as a new entry in the ich_chipset list.

Lewisburg is very similar to Sunrise Point for Flashrom's purposes,
however one important difference is the way the "number of masters" is
interpreted from the flash descriptor (0-based vs. 1-based).
