  vfio/display: add edid support.

This patch adds EDID support to the vfio display (aka vgpu) code.
When supported by the mdev driver qemu will generate a EDID blob
and pass it on using the new vfio edid region.  The EDID blob will
be updated on UI changes (i.e. window resize), so the guest can
adapt.

  vfio/display: add xres + yres properties

This allows configure the display resolution which the vgpu should use.
The information will be passed to the guest using EDID, so the mdev
driver must support the vfio edid region for this to work.

  vfio/display: delay link up event

Kick the display link up event with a 0.1 sec delay,
so the guest has a chance to notice the link down first.
