Revert "PCI: use ACPI _CRS data by default"

This reverts commit 9e9f46c44e487af0a82eb61b624553e2f7118f5b.

Quoting from the commit message:

 "At this point, it seems to solve more problems than it causes, so let's
  try using it by default.  It's an easy revert if it ends up causing
  trouble."

And guess what? The _CRS code causes trouble.
