soc/intel/xeon_sp/smihandler: Lock SMM_FEATURE_CONTROL on all sockets

Remove hardcoded B:D:F numbers for the first socket and pass the PCI
addresses to be locked within SMM by using the smm_pci_resource_store.

This allows to lock down SMM on all sockets without knowing the actual
bus topology or PCI segment group at compile time where the UBOX devices
reside on.

Tested: SMM is locked on all 4 sockets instead of just one.
