sample: vfio bochs vbe display (host device for bochs-drm) 



Display device, demo-ing the vfio dmabuf display interface
(VFIO_GFX_PLANE_TYPE_DMABUF).  Compatible enough to qemu stdvga
that bochs-drm.ko can be used as guest driver.

	  Build a virtual display sample driver for use as a VFIO

	  mediated device.  It supports the region display interface

	  (VFIO_GFX_PLANE_TYPE_DMABUF).

	  Emulate enough of qemu stdvga to make bochs-drm.ko happy.

	  That is basically the vram memory bar and the bochs dispi

	  interface vbe registers in the mmio register bar.

	  Specifically it does *not* include any legacy vga stuff.

	  Device looks a lot like "qemu -device secondary-vga".
