[PATCH] clk: test: Forward-declare struct of_phandle_args in kunit/clk.h

[Richard Fitzgerald <rf@opensource.cirrus.com>]

Add a forward-declare of struct of_phandle_args to prevent the compiler
warning:

../include/kunit/clk.h:29:63: warning: ‘struct of_phandle_args’ declared
inside parameter list will not be visible outside of this definition or
declaration
   struct clk_hw *(*get)(struct of_phandle_args *clkspec, void *data),
