Subject: Revert "drm/radeon: don't share plls if monitors differ in audio
 support"

commit 6fb3c025fee16f11ebd73f84f5aba1ee9ce7f8c6 upstream.

This reverts commit a10f0df0615abb194968fc08147f3cdd70fd5aa5.

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