drm/radeon/kms: rework spread spectrum handling
This patch reworks spread spectrum handling to enable it
properly on lvds and DP/eDP links. It also fixes several
bugs in the old spread spectrum code.
- Use the ss recommended reference divider if available
when calculating the pll
- Use the proper ss command tables on pre-DCE3 asics
- Avoid reading past the end of the ss info tables
- Enable ss on evergreen asics (lvds, dp, tmds)
- Enable ss on DP/eDP links
