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.
Connector type. Full size and mini connectors are identical except for the connector size and form, so I believe there is no functional need for this property. But similar to 'label' property, it might be used to present information about the connector to the userspace.
No eDP. There's really no "eDP connector", as it's always a custom made connection between the DP and the DP panel, although the eDP spec does offer a few suggested pin setups. 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++. DP++ might need an i2c bus added to the bindings.
