gpio: mxc: Use helper function devm_clk_get_optional_enabled()
Since commit 7ef9651e9792 ("clk: Provide new devm_clk helpers for
prepared and enabled clocks"), devm_clk_get_optional() and
clk_prepare_enable() can now be replaced by
devm_clk_get_optional_enabled() when the 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.
