[PATCH 3/5] venus: pm_helpers: Set opp clock name for v1

[Stanimir Varbanov]

The rate of the core clock is set through devm_pm_opp_set_rate and
to avoid errors from it we have to set the name of the clock via
dev_pm_opp_set_clkname.

Fixes: 9a538b83612c ("media: venus: core: Add support for opp tables/perf 
voting")
