Looks like the following is needed to avoid the error, no idea why..
But this is what we also do in omap-serial.c. It may be needed in
other places too?

Yes, there was a third one on shutdown.

Also, no luck yet on runtime PM. If the console is enabled omap won't
idle, and if no serial console is enabled, it just hangs. Will try
to debug this part further, it may be also related to the above.

My beaglebone xm won't do idle:

| omap3_pm_off_mode_enable: Core OFF disabled due to errata i583

but it would if it could, right? That means that I can't test the wake
via UART on this one?

So I will try to fix the tx-pm, fold patches and then prepare another
batch.
And I could verify that DMA works on that omap3 :)
