Tue May 17 04:54:12 PDT 2016
This new device tree file is to support pruss with uio based drivers
alone.
Adds uio entries for pruss susbsystem and disables other drivers
controlling the same.
New dtb is added only if ENABLE_TI_UIO_DEVICES is enabled.
Signed-off-by: Sam Nelson <sam.nelson at ti.com>

Change from previous version of patch
- Moved dtb add to ti-uio.inc
