[PATCH] serial: sccnxp: Use devm_clk_get_enabled() helper

[Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>]

The devm_clk_get_enabled() helper:
   - calls devm_clk_get()
   - calls clk_prepare_enable() and registers what is needed in order to
     call clk_disable_unprepare() when needed, as a managed resource.

This simplifies the code.
This also avoids some other warnings/issues. (see [1])
