Subject: [PATCH v3 0/4] Various fixes for the da9052 watchdog

Add support for the nowayout and timeout module parameters and treat
them in a standard way.

Respect twdmin, without this the watchdog timer will immediately assert
TWD_ERROR and power down to reset mode.

Do not stop the watchdog during probe. If the watchdog is enabled in the
bootloader, it should propably supposed to stay on.
