[PATCH] x86: efi_loader: Ensure the SMBIOS tables are sent via EFI

[Simon Glass]

The EFI-loader code has not been fully converted to use bloblist, so
relies on the SMBIOS-table address being set in global_data.

Set this up in write_tables() so that the SMBIOS tables are actually
available.

Enable the command for x86 QEMU so that the SMBIOS tests actually run.
