Subject: [PATCH v2] arm64: dts: ti: k3-am64-main: add timesync router node

The Time Sync Event Router (TIMESYNC_INTRTR0) implements a set of
multiplexers to provide selection of active CPTS time sync events for
routing to CPTS capable modules.

This patch adds DT node TIMESYNC_INTRTR0 using "pinctrl-single" bindings.
