watchdog: rzn1: 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 and avoids the need of a dedicated function used
with devm_add_action_or_reset().
