Exports the EDID via sysfs for user-space compositors. EDID information is not always available. Depending on the system and kernel configuration, it is either provided by the boot loader or read by the kernel during early boot stages. As of now, there's only one EFI display, so that EDID data always belongs to this output. This might change if there's ever more than one EFI display in the system.
