[PATCH RFC 08/12] arm64: dts: mediatek: mt8192-asurada: Add USB type-A connector

[Chen-Yu Tsai <wenst@chromium.org>]

The MT8192 Asurada design features a USB type-A connector for external
devices.

Add a proper representation for it with a node for the connector and
OF graph connection to the USB hub behind it.
