    console: support integrated 7-segment displays for POST codes
    
    Add a configuration option BOARD_POST and for use by mainboard
    Kconfig code BOARD_HAS_POST_DEV and MAINBOARD_POST_PORT to
    allow printing POST codes on 7-segment displays on some mainboards
    which are connected to an I/O port.
    For example the Abit AV8 has a POST display on port 0xE8.
