These are needed for small LCDs (e.g. 320x240). Also inserts some intermediate steps between pre-existing frequencies. The problem was the insertion of intermediate steps into the frequency table; they would cause the wrong frequency to be matched. This patch drops those intermediate frequencies while keeping the sub-25MHz frequencies.
