Currently, the wdt_reboot driver always gets its watchdog device reference from an OF node. This prevents selecting a watchdog at runtime. Move the watchdog device reference to the plat data, so the driver can be bound with the reference pre-provided. The reference will still be acquired from the OF node if it is not already provided.
