ASOC: rockchip: Use helper function devm_clk_get_enabled()

Browse Source 
Since commit 7ef9651e97 ("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 the clocks for the
whole lifetime of the device. Moreover, it is no longer necessary to
unprepare and disable the clocks explicitly.
