drm/radeon/kms: hopefully fix pll issues for real (v3)

commit 5b40ddf888398ce4cccbf3b9d0a18d90149ed7ff upstream.

The problematic boards have a recommended reference divider
to be used when spread spectrum is enabled on the laptop panel.
Enable the use of the recommended reference divider along with
the new pll algo.

v2: testing options

v3: When using the fixed reference divider with LVDS, prefer
min m to max p and use fractional feedback dividers.
