u-boot: Add mainline u-boot version 2014.07-rc3

* The latest mainline u-boot works well for most TI devices and
  we want to enable more people to use and test it.  Adding
  version 2014.07-rc3 will allow more people to build and use this
  u-boot version
* Add a dependency on dtc-native since the latest mainline of u-boot
  now requires this and not every build host will have the right
  version.
