recipes-kernel: Add GLSDK specific kernel tree for omap-a15

* Machine compatible with only omap-a15 devices.
* The TI Staging tree will not be used to maintain K3.8. Instead,
  this new tree is set up as a production tree. Pending features
  for 3.8 will be implemented on this tree.
  - Backported features from linux mainline
  - Backported bug-fixes from linux mainline and linux-stable.
  - Features implemented by the GLSDK team which maybe product
    specific.
  This is the tree on which GLSDK kernel releases will be made.
* This recipe is based off the Core SDK 2013.04.02 released kernel
