v3 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 v2:
- Use gpio-backlight
Since v1:
- Rebased on 3.15-rc4 + recent patches from Tomi

Hi,

Do you have any more comments on these? If no, do you want to pull them through your tree for 3.16, as discussed with Tony?

Regards,
