The driver should ideally be removed and we should use bcm7038_wdt.c
moving forward. Rafal, is this something you can try on 4908?

We would have to pay attention to arch/mips/bcm63xx/dev_wdt.c and
introduce a MODULE_DEVICE_TABLE() and platform_device_id so we can key
off any BCM63xx-specific behavior.
