clk: fixed-rate: Add support for specifying parents via DT/pointers

Browse source

After commit fc0c209c14 ("clk: Allow parents to be specified without
string names") we can use DT or direct clk_hw pointers to specify
parents. Create a generic function that shouldn't be used very often to
encode the multitude of ways of registering a fixed rate clk with
different parent information. Then add a bunch of wrapper macros that
only pass down what needs to be passed down to the generic function to
support this with less arguments.
