hal: renesas: smartbond: Do not freeze watchdog when enabled

Code was freezing watchdog after waking up from deep sleep.
After first deep sleep watchdog was disabled and in case
of lockup platform would not reset as expected.

Freezing should be done only if watchdog was disabled for build.
In case where Zephyr will feed watchdog there is no
need to freeze it.
