mb/ocp/monolake: use VPD data to configure FSP UPD
Summary: This patch calls monolake board specific function to query settings stored in VPD binary blob to configure FSP UPD variable HyperThreading.
Test Plan: * Build an OCP MonoLake coreboot image, run following command to initialize RW_VPD and insert HyperThreading key: vpd -f build/coreboot.rom -O -i RW_VPD -s 'HyperThreading=0' * Flash the image to MonoLake, boot and observe following message in boot log: Detected 16 CPU threads
If RW_VPD partition does not exist, or if HyperThreading key/value pair does not exist, the boot log has: Detected 32 CPU threads
