ACPICA: Tables: Restore old behavor to favor 32-bit FADT addresses.
commit 85dbd5801f62b66e2aa7826aaefcaebead44c8a6 upstream.
We need to find a smarter way to switch to 64-bit FADT addresses according
to the bug report. This patch reverts Linux to the original behavior.
Fixes: 0249ed2444d6 (ACPICA: Add option to favor 32-bit FADT addresses.)
