edid: Use a better mode for 640x480
The hardcoded clock value for 640x480 was 25.175 MHz. That's a valid
clock to use, but is quite hard to make a non-jittery clock from PLLs.
It's much easier to make 25.200 MHz, so let's do that.
The difference between the two modes is 59.9 Hz vs. 60 Hz and it seems
better to make a non-jittery 60 Hz rather than a very jittery 59.9 Hz.
BRANCH=none
BUG=chrome-os-partner:46256
TEST=Insignia monitor works, so do others
