Bug description:
  [ Impact ]

  The fbdev subsystem has been deprecated for a long time. We should
  drop it in favour of using simpledrm with fbdev emulation layer.

  This requires Kernel config changes:

  FB_EFI=n
  FB_VESA=n

  fbcon will still require FB to be available, but will use the fbdev
  emulation layer

  [ Test Plan ]

  * Ensure that systems currently relying on fbdev (and therefore only
  allowing Xorg logins) such as some virtual machine types, boot with
  working Wayland support.

  [ Where Problems could occur ]

  * When this stack is enabled, it changes boot timing such that some drivers 
may take a longer time to boot and GDM may hang in a black screen (bug 2039757).
  * Race conditions could be exposed to DE environments
  * Software that expects to find DRM device at /dev/dri/card0 may have a 
problem.
  * Some older versions of NVIDIA driver might not work properly.

  [ Other Info ]

  * Fedora bug: https://bugzilla.redhat.com/show_bug.cgi?id=2022385
