OMAPDSS: TPO-TD03MTEA1: adjust timings

These new timings reduce .vfp to 0 to eliminate the time window between
VFP and vsync as explained here:
http://processors.wiki.ti.com/index.php/OMAP35x_Linux_-_DSS_FAQ
Vsyned programs now also have ~1.25ms more time to finish the frame and
perform a fbdev pan operation before DSS reads out the registers.

Note that on pandora, /usr/pandora/scripts/op_lcdrate.sh needs
to be updated too.
