Christophe JAILLET 8f08553e7e rtc: k3: Use devm_clk_get_enabled() helper ...

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, the error handling paths and avoid the need of
a dedicated function used with devm_add_action_or_reset().

Based on my test with allyesconfig, this reduces the .o size from:
   text	   data	    bss	    dec	    hex	filename
   12843	   4804	     64	  17711	   452f	drivers/rtc/rtc-ti-k3.o
down to:
   12523	   4804	     64	  17391	   43ef	drivers/rtc/rtc-ti-k3.o
