[PATCH] ARM: davinci: fix DT booting with default defconfig

[Kevin Hilman]

Davinci boards tend to have older booloaders without DTB support.
Enable appended DTB support by default to allow DT booting on older
platforms. While there, also enable /proc/device-tree support for
easy verification of DT boot.

Sekhar, this applies on top of your latest defconfig cleanup queued
for v3.15 and validated with DT and legacy boot on DA850 EVM.

Thanks Kevin. If you will take this directly through ARM-SoC:

I'd prefer if you just take it along with your changes. Maybe as a
fix for v3.15-rc since it fixes some booting issues with legacy
booting on top of your defconfig cleanup.
