[nrf fromlist] soc: nordic: enable CONFIG_PM_DEVICE_RUNTIME_DEFAULT_ENABLE for all

Enable CONFIG_PM_DEVICE_RUNTIME_DEFAULT_ENABLE by default for all
nordic SoCs if CONFIG_PM_DEVICE_RUNTIME is used. This will ensure
consistent behavior across all nordic SoCs and remove the need
for pasting the devicetree propert zephyr,pm-device-runtime-auto
everywhere.
