dt-bindings: display: Add ITE IT61620 MIPI DSI to HDMI bridge

This chip receives MIPI DSI input and outputs HDMI, and is commonly
connected to SoCs via I2C and DSI. IT61620 uses a separate compatible
string from IT6162 due to architectural differences.

[Severity: Low]
Should this data-lanes property include a local constraint to enforce the
hardware limit of 4 lanes?

If a user configures a device tree with 5 to 8 lanes, it seems dt_binding_check
will incorrectly accept it. The endpoint schema inherits the generic limit of 8
from video-interfaces.yaml without imposing the local hardware limit.
