[flashrom] New Intel Chipsets

[Wagner, Helge (GE Intelligent Platforms)]

I have added support for some new intel chipsets.

(At least) for the QM57 which i have tested an additional patch was
needed as some reserved bits in the "Software Sequencing Flash Control
Register" (SSFC) needs to be programmed to 1 in the QM57.
