[PATCH V2] dt-bindings: watchdog: brcm, bcm7038: add more compatible strings

From: Rafał Miłecki <rafal at milecki.pl>

This hardware block is used on almost all BCM63xx family chipsets and
BCM4908 which reuses a lot of BCM63xx parts. Add relevant compatible
strings and also include a generic one.

The only SoC with a different block I found is BCM6838 (thus not included
in this change).

It may be worth noting that BCM6338, BCM6345, BCM6348 and BCM63268 don't
include "SoftRst" register but that can be handled by drivers based on
precise compatible string.
