Poddar, Sourav Sept. 24, 2013, 7:28 a.m. UTC 
This patch disables devices initially(status = "disabled").
Devices will only be probed, if the devices are
present in the board file(status = "okay").

Signed-off-by: Sourav Poddar <sourav.poddar@ti.com>
---
v1->v2:
change approach to disabling devices in dtsi and
enable it in respective board file.
