Expose EDID fields in DeviceProductInfo
Expose product-specific information (display name, manufacture date,
manufacturer Pnp ID) about the display or the directly connected device
on the display chain. For example, if the display is transitively
connected, these fields may contain product information about the
intermediate device.
Additionally this information can be used to prime a TV with entries
from an infrared database for controlling connected audio and TV devices.
