[PATCH v8 1/8] clk: test: export clk_dummy_rate_ops and clk_dummy_context() for other tests

[Brian Masney <bmasney@redhat.com>]

Expose clk_dummy_rate_ops and struct clk_dummy_context so that they can
be used for other clk kunit tests.

This export will be used by the upcoming clk-divider test suite. For
consistency with clk-fixed-rate_test.c and drivers/clk/clk-gate_test.c,
the divider tests will be setup as it's own separate kernel module.

The file kunit/clk.h now contains a struct clk_hw embedded by value. If
kunit/clk.h is included before linux/clk-provider.h, then this will
yield a compiler error since it won't know the size of struct clk_hw.
Let's also go ahead and include clk-provider.h since it's a dependency
here, and this lets us drop the 'struct clk' and 'struct clk_hw' at the
top that are no longer needed.
