VPD: Adding the Virtual Product Data detection
Impact: It's now possible to reach VPD's info Calling vpd_decode() populate a VPD structure to display : - VPD's base address - Bios Build ID - Bios Release Date - Bios Version - Box Serial Number - Motherboard Serial Number - Machine Type/Model - Default Flash Filename
