[PATCH 1/3] dt-bindings: watchdog: convert Broadcom's WDT to the json-schema

["Rafał Miłecki" <zajec5@gmail.com>]

From: Rafał Miłecki <rafal@milecki.pl>

This helps validating DTS files. While at it also rename it to bcm63xx.
It's the first SoC with that hardware block and it's a naming schema
used for other Broadcom blocks. It's common for some (originally)
bcm63xx blocks to be reused in newer SoCs (like 7038 or 4908).
