Jens Rottmann 82f55af06a 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.
