I wasn't sure if I should proceed with bcm63xx_wdt.c or bcm7038_wdt.c so
I chose 63xx. Possibly a bad decision, I'm not sure.

I've already bcm63xx_wdt.c changes developed locally to support BCM4908.
I just need to add Documentation/dt-bindings/ part. I'll do that
tomorrow. Then you can let me know if that's acceptable or should I
refactor my changes.
