viafb: split pll configs up
This patch splits the pll configs up on pll versions. This allows easy adding of other known good pll values. Additionally it made it possible to remove invalid configurations resulting in better behaviour for such cases. The resulting clocks are no longer stored resulting in some computing overhead on each mode change. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
