ARM: tegra: Fix I2C bus frequencies on Apalis/Colibri
Use a faster speed of 400 kbit/s for regular I2C busses.
Use a slower speed of 10 kbit/s for DDC/EDID to improve reliability.
Use a slower speed of 100 kbit/s for power I2C to be within specs of
the LM95245 temperature sensor.
While at it further annotate I2C pin usage.
