drivers/intel/fsp2.0: Add semantic patch for FspUpdVpd.h header

Previous FSP implementations in coreboot have included FspUpdVpd.h
directly, along with with efi headers. Instead of taking that
approach in FSP 2.0, we provide a semantic patch that, with minimal
modifications, makes FspUpdVpd.h easier to include in coreboot, and
eliminates reliance on external headers and definitions.
