soc/intel/xeon_sp: Find VTD devices by PCI DEV ID

Instead of manually crafting S:B:D:F numbers for every
VTD device loop over the entire devicetree by PCI DEV IDs.

This adds PCI multi-segment support without any further code
modifications, since the correct PCI segment will be stored in the
devicetree.
