[PATCH 5/6] mips: dts: ralink: mt7620a: update system controller node and its consumers

[Sergio Paracuellos]

Current MT7620A device tree file is out of date and must be merged with real
device tree file used in openWRT project [0]. As a first iteration for this
changes, align the current file with the needed changes for system controller
from '6f3b15586eef ("clk: ralink: add clock and reset driver for MTMIPS SoCs")'.
