Subject: [PATCH 3/9] video: sysfb: always provide vbefb device

From: David Herrmann <dh.herrmann@...glemail.com>

HACK: This should be provided by architecture setup code. But to show how it is
supposed to work, we now simply add a "vbefb" device during initialization.

The better way to do this is by moving this into arch-code. So for instance the
x86 boot initialization should create this platform-device after VBE/VESA screen
detection. Other architectures can do the same or introduce other framebuffer
types than SYSFB_VBE.
