clk: clk-loongson2: Switch to use devm_clk_hw_register_fixed_rate_parent_data()

Since commit 706ae64 ("clk: fixed-rate: add
devm_clk_hw_register_fixed_rate_parent_data()"), we can use the
devm_clk_hw_register_fixed_rate_parent_data() helper and from then on
there is no need to manually unregister the fixed rate hw.

Since clk_hw_unregister_fixed_rate() was not called before, we also fix
the memory leak that was present.
