The horizontal resolution (640) for the TT High video mode (1280x960) is
definitely bogus. While fixing that, correct the timings to match the
TTM195 service manual.

Untested on actual hardware.
v3:
- Adjust pixclock from 7761 to 7760 to match 4 * 32.215905 MHz
crystal oscillator frequency,
- Make it part of a series.
v2[1]:
- Use correct base.
