According to clk_ops struct definition, the callback `get_rate()` return current clock rate value as ulong. `clk_get_rate()` should handle the clock rate returned as ulong also.
Otherwise we may have invalid/truncated clock rate value returned by `clk_get_rate()`.
`log_ret` has also been removed since it use an `int` in the macro definition.

Thanks for the review, I appreciate it.
I would prefer to create a new log_rete() to handle this, with a long argument and return value. But this is OK, I suppose.
Yes and I guess that could be used in other functions in clk-uclass.c
