[PATCH v10 0/8] NVIDIA Tegra power management patches for 5.16

[Dmitry Osipenko]

This is a reduced version of the patchset which adds power management
support to NVIDIA Tegra drivers. 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().
