Subject: [PATCH 07/20] smbios: get rid of smbios_smp_sockets global

RH-Author: Igor Mammedov <imammedo@redhat.com>
RH-MergeRequest: 230: Workaround Windows failing to find 64bit SMBIOS entry point with SeaBIOS
RH-Jira: RHEL-21705

RH-Commit: [5/18] f59bfeb547b7febcf1de2b6179af006e7fa0bccd

JIRA: https://issues.redhat.com/browse/RHEL-21705

    it makes smbios_validate_table() independent from
    smbios_smp_sockets global, which in turn lets
    smbios_get_tables() avoid using not related legacy code.

Conflicts:
   include/hw/firmware/smbios.h due to down-stream
   (d9ff466c980d Machine type related general changes)
    adding custom stream_product/stream_version
