Subject: [PATCH net-next 4/5] arm64: dts: ti: k3-am62-main: Add timesync router node

TI's AM62x SoC has a Time Sync Event Router, which enables routing a single
input signal to multiple recipients. This facilitates syncing all the
peripherals or processor cores to the input signal which acts as a master
clock.
