Use the newly created wrapper drm_fb_helper functions instead of calling
core fbdev functions directly. They also simplify the fb_info creation.
v3:
- Don't touch remove_conflicting_framebuffers
v2:
- add missing header for virtgpu_fb.c

This should avoid issues with the fbdev path trying to render
before we've gotten the display info.

The goto is correct, and we never reach the return statement so just
delete the dead code.

virtio_gpu_alloc_object() returns an error pointer, it never returns
NULL.

This patch adds a kms driver for the virtio gpu. The xorg modesetting
driver can handle the device just fine, the framebuffer for fbcon is
there too.
Qemu patches for the host side are under review currently.
The pci version of the device comes in two variants: with and without
vga compatibility. The former has a extra memory bar for the vga
framebuffer, the later is a pure virtio device. The only concern for
this driver is that in the virtio-vga case we have to kick out the
firmware framebuffer.
Initial revision has only 2d support, 3d (virgl) support requires
some more work on the qemu side and will be added later.
