    clk: convert API to match reset/mailbox style · 135aa950

    The following changes are made to the clock API:
    * The concept of "clocks" and "peripheral clocks" are unified; each clock
      provider now implements a single set of clocks. This provides a simpler
      conceptual interface to clients, and better aligns with device tree
      clock bindings.
    * Clocks are now identified with a single "struct clk", rather than
      requiring clients to store the clock provider device and clock identity
      values separately. For simple clock consumers, this isolates clients
      from internal details of the clock API.
    * clk.h is split so it only contains the client/consumer API, whereas
      clk-uclass.h contains the provider API. This aligns with the recently
      added reset and mailbox APIs.
    * clk_ops .of_xlate(), .request(), and .free() are added so providers
      can customize these operations if needed. This also aligns with the
      recently added reset and mailbox APIs.
    * clk_disable() is added.
    * All users of the current clock APIs are updated.
    * Sandbox clock tests are updated to exercise clock lookup via DT, and
      clock enable/disable.
    * rkclk_get_clk() is removed and replaced with standard APIs.
    Buildman shows no clock-related errors for any board for which buildman
    can download a toolchain.
