The other thing I forgot to mention is that I think we should allow
installing new tables even if CONFIG_ACPI_INITRD_TABLE_OVERRIDE is not
selected. IMO the override and overlay functionality is different,
with the latter being more then a debug option.

I will prepare a patch for the next version of the series to decouple
installing new tables from CONFIG_ACPI_INITRD_TABLE_OVERRIDE.
