Use devm_clk_get_optional_enabled() helper instead of calling
devm_clk_get_optional() and then clk_prepare_enable(). It simplifies
the error handling and makes the code more compact. This changes removes
the unnecessary clk variable and assigns the result of the
devm_clk_get_optional_enabled() call directly to pcie->refclk.
This makes the code more concise and readable without changing the
behavior.
