4.0-stable review patch.  If anyone has any objections, please let me know.

From: Alex Deucher <alexander.deucher@....com>

commit 6fb3c025fee16f11ebd73f84f5aba1ee9ce7f8c6 upstream.

This reverts commit a10f0df0615abb194968fc08147f3cdd70fd5aa5.

Fixes some systems at the expense of others.  Need to properly
fix the pll divider selection.
