spi: spi-fsl-dspi: Use helper function devm_clk_get_enabled()
Since commit 7ef9651e9792 ("clk: Provide new devm_clk helpers for prepared and enabled clocks"), devm_clk_get() and clk_prepare_enable() can now be replaced by devm_clk_get_enabled() when driver enables (and possibly prepares) the clocks for the whole lifetime of the device. Moreover, it is no longer necessary to unprepare and disable the clocks explicitly.
