It is useful to show a boot logo when starting up. Add the BGRT table
after the QEMU-provided tables.

emulation: Improve ACPI support for qemu-x86_64
When running under QEMU U-Boot obtains its ACPI tables from QEMU, since
it has the require information. This works well in most cases.
QEMU also provides SMBIOS tables, but U-Boot doesn't currently use those
on x86. This creates problems if a VM environment is expecting to see
particular values (e.g. those which it passed to QEMU!) when booting. So
this series switches QEMU on x86 to use those SMBIOS tables.
Finally, there is a facility in EFI for showing a boot logo, via a BGRT
table. QEMU does not provide this itself, so this series augments the
ACPI tables with a new BGRT table containing a suitable logo.
