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.
Signed-off-by: Geert Uytterhoeven geert@linux-m68k.org --- 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.
