OPP: Fix parsing of multiple phandles in "operating-points-v2" property
We currently return error if more than one phandle is present in the "operating-points-v2" property, which is incorrect. We only want to check the count of phandles here and set index to 0 if only one phandle is present. Fix it. Fixes: 5ed4cecd75e9 ("OPP: Pass OPP table to _of_add_opp_table_v{1|2}()") Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>
