Subject: [PATCH v3 2/9] clk: test: introduce clk_dummy_rate_mhz()

Some of the mock tests care about the relationship between two
different rates to ensure that functionality in the clk core is
exercised when the parent rate is negotiated by using specific
rates. Introduce clk_dummy_rate_mhz() to improve readability.
Change the DUMMY_CLOCK_* rate constants over to use this.
