drm/mediatek: Add mt8195 DisplayPort driver

This patch adds a DisplayPort driver for the Mediatek mt8195 SoC. It supports both functional units on the mt8195, the embedded DisplayPort as well as the external DisplayPort units. It offers hot-plug-detection, audio up to 8 channels, and DisplayPort 1.4 with up to 4 lanes. This driver is based on an initial version by Jason-JH.Lin <jason-jh.lin@mediatek.com>. Signed-off-by: Markus Schneider-Pargmann <msp@baylibre.com>
