Jarkko Nikula 9ce7610e6d i2c: designware: Call i2c_dw_clk_rate() only when calculating timings
There are platforms which don't provide input clock rate but provide
I2C timing parameters. Commit 3bd4f27727 ("i2c: designware: Call
i2c_dw_clk_rate() only once in i2c_dw_init_master()") causes needless
warning during probe on those platforms since i2c_dw_clk_rate(), which
causes the warning when input clock is unknown, is called even when
there is no need to calculate timing parameters.

Fixes: 3bd4f27727 ("i2c: designware: Call i2c_dw_clk_rate() only once in i2c_dw_init_master()")
