v4: added ti,bootreg-shift and ti,autosuspend-delay properties

You missed out on my v3 comment on the firmware-name on Example 2. Can
you please address it when you post the next version?

I don't think I missed it, but you never told what is the actual name to use there. Firmware name generally does not matter, as user can provide whatever he wants via DT now.
