chipset_enable: Add support for C620-series Lewisburg PCH

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

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). There are
also new flash regions defined.
