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.
