  smbios: rename/expose structures/bitmaps used by both legacy and modern code
  smbios: add smbios_add_usr_blob_size() helper
  smbios: don't check type4 structures in legacy mode
  smbios: avoid mangling user provided tables
  smbios: get rid of smbios_legacy global
  smbios: get rid of smbios_smp_sockets global
  smbios: cleanup smbios_get_tables() from legacy handling
