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

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.
