Viresh Kumar asked to send these PD/OPP patches separately for now to reduce the noise and finalize the review. I implemented new dev_get_performance_state() GENPD callback as was discussed in v8/v9. GR3D driver patch shows how it's used by consumer drivers. v10: - Replaced dev_pm_opp_from_clk_rate() with dev_pm_opp_get_current(), as was requested by Viresh Kumar. - Added more comments to the code and extended commit message, as was requested by Viresh Kumar and Ulf Hansson. - Renamed get_performance_state() to dev_get_performance_state(), as was requested by Ulf Hansson. - Factored out 'performance' code out of __genpd_dev_pm_attach() into a separate function genpd_dev_initialize_performance_state(), as was requested by Ulf Hansson. - Removed dev_suspended argument from dev_get_performance_state(), as was requested by Ulf Hansson. It's replaced by the usage of pm_runtime_status_suspended(), see genpd_dev_get_current_performance_state().
