Follow the dp-connector example and add hdmi-pwr supply to drive the 5V
pin of the HDMI connector (together with some simple glue logic possibly
attached to the connector).

The meta-schema recently gained a definition for the common -supply$
property, which denotes that maxItems is not a valid property. Drop this
to clear up the binding validation error.

Now that we have a graph schema, rework the display related schemas to use
it. Mostly this is adding a reference to graph.yaml and dropping duplicate
parts from schemas.
In panel-common.yaml, 'ports' is dropped. Any binding using 'ports'
should be one with more than 1 port node, and the binding must define
what each port is.
Note that ti,sn65dsi86.yaml, ti,tfp410,yaml and toshiba,tc358768.yaml will
need further updates to use video-interfaces.yaml once that lands.

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.

Some connectors no matter if in- or output supports only a limited
range of sdtv standards. It doesn't matter if the hardware behind that
connector supports more than the listed formats since the users are
restriced by a label e.g. to plug only a camera into this connector
which uses the PAL format.
This patch adds the capability to describe such limitation within the
firmware. There are no format restrictions if the property isn't
present, so it's completely backward compatible.

Some Allwinner SoC using boards (Orange Pi 3 for example) need to enable
on-board voltage shifting logic for the DDC bus using a gpio to be able
to access DDC bus. Use ddc-en-gpios property on the hdmi-connector to
model this.
Add binding documentation for optional ddc-en-gpios property.

This is a quite large renaming to consolidate display related bindings
into a single "display" directory from various scattered locations of
video, drm, gpu, fb, mipi, and panel. The prior location was somewhat
based on the Linux driver location, but bindings should be independent
of that.
