v2 cover ARM: dts: overo: Add panel support

Hi,

This series enables the DVI and LCD panels present on some of the Overo expansion boards.

DVI output:
- Tobi
- Summit

LCD (3.5''):
- Alto35

LCD (4.3''):
- Chestnut43
- Palo43
- Gallop43

I tested on Tobi, Alto35 and Gallop43.

This series depends on several patches from Tomi [1][2][3] targeting 3.16.

Regards,
Florian

Since v1:
- Rebased on 3.15-rc4 + recent patches from Tomi

PATCH v2 2/3 ARM: dts: overo: Add support for 4.3'' LCD output

In reply to Florian Vaussard

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.

The panel-dpi only takes one gpio, the enable. The backlight should be handled with gpio-backlight driver.

The same applies for the Alto35 patch.
