soc/intel/cannonlake: Add VrPowerDeliveryDesign to chip options
Intel introduced the UPD VrPowerDeliveryDesign with Cannon Lake. The
BIOS needs to program VrPowerDeliverDesign configuration per platform
according to the platform capabilities to avoid incorrect
electrial/power parameters. This is only added for Cannon Lake.
Refer to document 599797 for more details.
