[LEDE-DEV] [PATCH v2] ramips: fix missing mediatek wdt

[Kevin Darbyshire-Bryant]

mediatek MT7621 soc watchdog DTS id was renamed from "mtk,mt7621-wdt" to
"mediatek,mt7621-wdt" when driver upstreamed to kernel 4.5

Update mt7621.dtsi & mt7628an.dtsi definitions to match upstreamed
kernel.

Restores hardward watchdog functionality on mt7621 devices under linux
4.9

Tested on: MIR3G
