On Falcon, Atari frame buffer initialization relies on preprogrammed
register values. These register values are changed to blank the
console.
Hence when using kexec to boot into a new kernel while the console is
blanked, the new kernel cannot determine the current video
configuration, and the Atari frame buffer driver fails to initialize:
atafb: phys_screen_base 6ce000 screen_len 4096
Fix this by doing a straight-forward conversion of the driver to a
platform device driver, and adding a shutdown handler that unblanks the
display.
