[ Upstream commit 020d86fc0df8b865f6dc168d88a7c2dccabd0a9e ]
The 'required-opps' property is considered optional, hence remove the pr_err() in of_parse_required_opp() when we find the property is missing. While at it, also fix the return value of of_get_required_opp_performance_state() when of_parse_required_opp() fails, return a -ENODEV instead of the -EINVAL.
