soc/intel/xeon_sp: Locate PCU by PCI device ID

Instead of manually crafting S:B:D:F numbers for each PCI device
search for the devices by PCI vendor and device ID.

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

Intel Document-ID: 735086
Intel Document-ID: 612246

Tested: On SPR 4S all PCU on all 4 sockets could be found and locked.
