fix "lxfb: extend PLL table to support dotclocks below 25 MHz"
The following patch caused a regression with OLPC panels: commit 3888d4639e78802c4ec1086127124e890461b9e4 lxfb: extend PLL table to support dotclocks below 25 MHz Extends the PLL frequency table of the AMD Geode-LX frame buffer driver to make use of the DIV4 bit, thus adding support for dotclocks between 6 and 25 MHz. 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.
