Summit and Tobi expansion boards have a HDMI connector with a TFP410
encoder. Add a common include file for this configuration, and then
use it for Summit and Tobi.

The i2c3 pins don't belong here, they are not related to dss. The
dvi-connector uses i2c3, but I don't think they belong there either, as
the i2c3 bus can be used by multiple devices. So I guess they should be
set in &i2c3 node.

You are right. And as I am already using i2c3 for other things, this
duplicates the pinctrl. I will drop it.

Chestnut43, Gallop43 and Palo43 expansion boards have a ZIF connector
for a 4.3'' LCD.Add a common include file for this configuration, and
use it on relevant expansion boards.
