[U-Boot] [PATCH v2 02/11] videomodes: Add (vesa) standard timings

The timings for the modes defined in videomodes.c differ (significantly)
from vesa standard timings for these modes.

This commit adds a version with the proper std timings for these modes,
since I do not want to cause regressions, boards which want to use the standard
timings need to define CONFIG_VIDEO_STD_TIMINGS to get the new correct timings.

Since there is no std timing for 960x720 this commit uses the timing used
by the nvidia video drivers for 960x720, which uses a standard pixelclock
of 74.25 MHz rather then the weird 76.335... clock used by the old modes.
