Subject: [PATCH 08/20] smbios: get rid of smbios_legacy 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-Acked-by: MST <mst@redhat.com>
RH-Acked-by: Ani Sinha <None>
RH-Commit: [6/18] 684dd1dca8d611c6de97b26ef8c1cda6ca509d54
JIRA: https://issues.redhat.com/browse/RHEL-21705
clean up smbios_set_defaults() which is reused by legacy
and non legacy machines from being aware of 'legacy' notion
and need to turn it off. And push legacy handling up to
PC machine code where it's relevant.

Conflicts: hw/arm/virt.c, hw/i386/fw_cfg.c, hw/loongarch/virt.c,
hw/smbios/smbios.c, include/hw/firmware/smbios.h
due to downstream specifc signature of smbios_set_defaults()
PS:
while fixing conflicts move RHEL specific
smbios_stream_product/smbios_stream_version
at the end of arguments list
