[PATCH v2 7/8] MIPS: Loongson64: dts: ls7a-pch: Add watchdog node

["Rong Zhang" <rongrong@oss.cipunited.com>]

The Loongson-7A has a watchdog compatible with the one on Loongson
2K0300.

Add a watchdog node with appropriate compatible strings to wire it up.

Tested on Loongson-LS3A4000-7A1000-NUC-SE and Lenovo KaiTian M530Z.
