linux-ti-staging: Add version 3.15 of TI integration kernel

* Add version 3.15 of the TI integration kernel.  Major changes
  from previous version are:
    * Config fragments now come primarily from the integration
      tree.  Removed baseport and connectivity fragments for now
      and the others can be removed as they are added to the
      integration tree.
    * Added a non-smp.cfg config to disable SMP for single core
      devices instead of using a patch to the defconfig file as
      we did in the past.
* Use the right SRCREV
