Make coreboot use the offset parameter in cbfstool create
On Sandybridge and Ivybridge systems the firmware image has to
store a lot more than just coreboot, including:
- a firmware descriptor
- Intel Management Engine firmware
- MRC cache information
This option allows to limit the size of the CBFS portion in
the firmware image.
