As part of the new SMBIOS and System Firmware code:
- Replace old dmi* structures and functions with new sysfw* and smbios*
structures and functions in individual drivers
- cleanup sysfw_id lookup tables
- add exactmatch functionality
- edit udev notifiers
- cleanup of includes for dmi.h and mod_devicetable.h which were included in
some files that did not need them
