Merge tag 'integrator-v3.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into next/dt

From Linus Walleij:
Two integrator device tree patches for v3.14:

- Delete some static core module mappings.

- Move EBI location to the device tree.

* tag 'integrator-v3.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator:
  ARM: integrator: move EBI to the device tree
  ARM: integrator: delete static core module mappings
