ACPICA: Tables: Restore old behavor to favor 32-bit FADT addresses.

commit 85dbd580 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: 0249ed24 (ACPICA: Add option to favor 32-bit FADT addresses.)
