rtc: jz4740: 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().

As a side effect, some error messages are not logged anymore, so also use
dev_err_probe() instead of dev_err() in case of error.
At least the error code will be logged (and -EPROBE_DEFER will be filtered)

Based on my test with allyesconfig, this reduces the .o size from:
   text	   data	    bss	    dec	    hex	filename
   9025	   2488	    128	  11641	   2d79	drivers/rtc/rtc-jz4740.o
down to:
   8267	   2080	    128	  10475	   28eb	drivers/rtc/rtc-jz4740.o
