soc/intel/cannonlake: Add FSP UPD for minimum assertion width
Expose the FSP tunables for the chipset minimum assertion width
settings which can be configured per-board.
The defaults appear to be different from what is listed in the FSP
header documentation so I tried to list what the actual default is
based on the source rather than what is stated the header comments.
