This allows the init sequence to correctly determine and store that the selected display device after autoselection was MAX7456 but it hasn't been yet initialized, and allows us to properly transmit this information to the configurator. This also lets the display subsystem initialize the MAX7456 at any time, so for example in flight controllers that require battery power in order to turn on the MAX7456, the user can plug the battery after powering the system up via USB and the MAX7456 will be detected shortly after without having to reboot.
