clk: Introduce clk_hw_init_rate_request()
clk-divider instantiates clk_rate_request internally for its round_rate
implementations to share the code with its determine_rate
implementations.
However, it's missing a few fields (min_rate, max_rate) that would be
initialized properly if it was using clk_core_init_rate_req().
Let's create the clk_hw_init_rate_request() function for clock providers
to be able to share the code to instation clk_rate_requests with the
framework. This will also be useful for some tests introduced in later
patches.
