Change in ...coreboot[master]: soc/intel/cannonlake: Enable all C states in FSP

Maulik V Vaghela has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/32463 Change subject: soc/intel/cannonlake: Enable all C states in FSP ...................................................................... soc/intel/cannonlake: Enable all C states in FSP FSP will not enable all C-states by default when we use FSP to do MP initialization. We need to set UPD from coreboot to enable C-states in FSP.
