[PATCH 2/3] mips: dts: ralink: mt7621: add phandle to system controller node for watchdog

[Sergio Paracuellos <sergio.paracuellos@xxxxxxxxx>]

To allow to access system controller registers from watchdog driver code
add a phandle in the watchdog 'wdt' node. This avoid using arch dependent
operations in driver code.
