Few fixes for omaps against v4.5-rc3:

- Improve omap_device error message to tell driver writers what is
  wrong after commit 5de85b9d57ab ("PM / runtime: Re-init runtime PM
  states at probe error and driver unbind"). There will be also a
  handful of driver related fixes also queued separately. But adding
  this error message makes it easy to fix any omap_device using
  drivers suffering from this issue so I think it's important to
  have.

- Also related to commit 5de85b9d57ab discussion, let's fix a bug
  where disabling PM runtime via sysfs will also cause the hardware
  state to be different from PM runtime state.

- Fix audio clocks for beagle-x15.

- Use wakeup-source instead of gpio-key,wakeup for the new entries
  that sneaked in during the merge window.

- Fix a legacy booting vs device tree based booting regression for
  n900 where the legacy user space expects to have the device
  revision available in /proc/atags also when booted with device
  tree.
