clk: Store clk_core for clk_rate_request 



The struct clk_rate_request is meant to store the context around a rate
request such as the parent, boundaries, and so on.

However, it doesn't store the clock the rate request is submitted to,
which makes debugging difficult.

Let's add a pointer to the relevant clk_core instance in order to
improve the debugging of rate requests in a subsequent patch.
