[PATCH v4 09/10] clk: add clk_rate_exclusive api

Using clock rate protection, we can now provide a way for clock consumer to claim exclusive control over the rate of a producer So far, rate change operations have been a "last write wins" affair. This changes allows drivers to explicitly protect against this behavior, if required. Of course, if
