Changes in v11:
    - fix pm_genpd_init(&pd->genpd, NULL, false);

Changes in v10:
    - this switches over domain infos to use masks instead of recomputing
      them each time and also gets rid of custom domain translator and
      uses standard onecell on.

Changes in v9:
    - fix v8 changes as follows:
    - This reconciles the v2 and v7 code so that we power domain have
      lists of clocks they toggle on and off during power transitions and
      independently from power domains clocks we attach clocks to devices
      comprising power domain and prepare them so they are turn on and off
      by runtime PM.
    - add rockchip_pm_add_one_domain() to control domains.
    - add pd_start/pd_stop interface to control clocks

Changes in v8:
    - This reconciles the v2 and v7 code so that we power domain have
      lists of clocks they toggle on and off during power transitions and
      independently from power domains clocks we attach clocks to devices
      comprising power domain and prepare them so they are turn on and off
      by runtime PM.

Changes in v7:
    - Delete unused variables

Changes in v6:
    - delete pmu_lock
    - modify dev_lock using mutex
    - pm_clk_resume(pd->dev) change to pm_clk_resume(ed->dev)
    - pm_clk_suspend(pd->dev) change to pm_clk_suspend(ed->dev)
    - add devm_kfree(pd->dev, de) in rockchip_pm_domain_detach_dev

Changes in v5:
    - delete idle_lock
    - add timeout in rockchip_pmu_set_idle_request()

Changes in v4:
    - use list storage dev

Changes in v3:
    - change use pm_clk_resume() and pm_clk_suspend()

Changes in v2:
    - remove the "pd->pd.of_node = np"

This was discussed offlist, but just to make sure it's also included here:

This patch will need to be spun to deal with the fact that (c16561e PM
/ Domains: Change prototype for the attach and detach callbacks) has
landed.
