Linux on ARM/arm64 will infer from the presence of a /chosen/stdout-path DT property or of a SPCR ACPI table that the primary console is the serial port, even if a graphical console is available as well. So let's introduce a driver that allows the user to set a preference between graphical and serial if both are available. If the preference is set to 'Graphical', and any GOP protocol instances have been installed by the time the ReadyToBoot event is signalled, remove the DT property and/or the SPCR table entirely.
