arm64: dts: ti: verdin-am62: disable MIPI DSI bridge

Keep the DPI to MIPI-DSI bridge disabled in the SoM dtsi file.

The display chain is not wholly described in the device tree file, on
Verdin product family the displays are additional accessories that are
configured/enabled using DT overlays.

With this enabled we have issues when a display is enabled on
TIDSS port1 (LVDS) and port0 (DSI) is not used.
