This series fixes the I2C bus frequencies, uses the correct compatible
for the RTC and removes an unneeded reg property for Tegra based
Toradex Apalis and Colibri modules.

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.

* [PATCH 2/3] ARM: dts: tegra: apalis/colibri: use correct compatible for rtc

All Toradex Carrier Boards use a st,m41t0 compatible RTC. Compared to a
st,m41t00 this RTC has also an oscillator fail bit which allows to
detect when the RTC lost track of time.
Similar to commit c53bec16b150 ("ARM: dts: colibri/apalis: use correct
compatible for RTC") covering our NXP i.MX and Vybrid based modules.

no 'reg' property under stmpe_touchscreen, so remove it to fix the
following build warning with W=1:
