[PATCH 3/4] arm64: dts: mediatek: Use DP AltMode defines

[Sebastian Reichel]

From: Sebastian Reichel <sebastian.reichel at collabora.com>

Use the new USB-C DP AltMode defines for the SVID and the capabilities
VDO to make the DTs more readable. This also fixes up mt8390 Genio
platform incorrectly announcing UFP_D (upwards facing) support. This
feature is unfortunately not supported by the SoC.
