So reset_control_status() could maybe return -EIO error if context was lost.
Or maybe something like reset_control_context_lost() could be implemented.
Needs to be discussed on the related mailing lists of course. Then omap_prm.c
just needs the context lost registers mapped, and consumer drivers can check
context lost status from the reset framework.
