nb/i945/gma.c: correct VSYNC end offset
According to "G45: Volume 3: Display Register Intel ® 965G Express
Chipset Family and Intel ® G35 Express Chipset Graphics Controller" the
VSYNC end should start at bit 16. This is also how Linux (at least 4.4)
sets this register, which can be seen with intel-gpu-tools.
TESTED on Lenovo thinkpad X60 (it does not change anything).
