This reverts commit c6d2b0fbb893d5c7dda405aa0e7bcbecf1c75f98.

This patch is a workaround for a hardware bug, but I don't
know that we've actually seen the hw bug triggered in practice,
meanwhile a number of people have reported that this causes
suspend and resume issues.

This patch should not have been applied to stable.  It depends
on changes in newer drivers.

This reverts commit 756fec062e4b823bbbe10b95cbcfa84f948131c6.
