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.
