soc/intel/xeon_sp/util: Enhance lock_pam0123
- Only compile code in ramstage
- Lock PAM on all sockets
- 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.
