SoC related changes for omaps for v3.17 merge window:

- Add device tree and hwmod data for various devices
  for new SoCs

- Remove legacy mailbox hwmod data that's no longer
  needed for SoCs that are DT only. Note that this may
  cause a minor merge conflict in mach-omap2/devices.c
  with omap_init_mbox() and omap_init_hdmi_audio(), both
  are legacy code that is getting removed
