Subject[PATCH V2 2/2] PM / Domains: Rename opp_node to np
Date
The DT node passed here isn't necessarily an OPP node, as this routine
can also be used for cases where the "required-opps" property is present
directly in the device's node. Rename it.

This also removes a stale comment.

V2:
- Updated variable name in header file as well.
- Because it was a very small change, I added Ulf's Ack as well.
