    kernel/pc64: Improve EFI framebuffer mapping.
    
    * Do a proper pmap_mapdev_attr() via SYSINIT after early boot stuff is
      finished.
    
    * Make sure the EFI framebuffer is covered by the direct map, when using
      PHYS_TO_DMAP to access the framebuffer as early as possible.
      If it isn't covered by the direct memory map, the framebuffer will later
      be properly mapped via pmap_mapdev_attr() anyway.
