Subject: [PATCH v3] Create pci slot files for SMBIOS Type 9 entries

The following diff builds on the "[PATCHv3] Save SMBIOS Type 9 System Slots"

This will create a /sys/bus/pci/slots/XXX file for each Type 9 entry.  This will be \
used for systemd enumeration of NICs.

Only build if CONFIG_DMI is set
