Add binding for DisplayPort connector. A few notes: * Similar to hdmi-connector, it has hpd-gpios as an optional property, as the HPD could also be handled by, e.g., the DP bridge. * dp-pwr-supply, which provides 3.3V on DP_PWR pin, is optional, as it is not strictly required: standard DP cables do not even have the pin connected. * No property for the connector type. Full size and mini connectors are identical except for the connector size and form, so I believe there is no need to include the type in the bindings. * No eDP. There's really no "eDP connector", as it's always a custom made connection between the DP and the DP panel. So possibly there is no need for edp-connector binding, but even if there is, I don't want to guess what it could look like, and could it be part of the dp-connector binding. * No DP++. I'm not familiar with DP++, but I think it's all handled by the DP bridge, and does not need any new properties to the dp-connector.
