Subject: [PATCH stable 6.1] MIPS: dts: bcm63268: Add missing properties to the TWD node

From: Florian Fainelli <f.fainelli@...il.com>

commit 24b333a866a10d4be47b9968b9c05a3e9f326ff5 upstream

We currently have a DTC warning with the current DTS due to the lack of
a suitable #address-cells and #size-cells property:

  DTC     arch/mips/boot/dts/brcm/bcm63268-comtrend-vr-3032u.dtb

The Fixes tag was partially incorrect which is why this change should
have been applied to the 6.1 stable tree, but it was not.
