This is a slight improvement for legacy flipping, but also an attempted
fix for a bug/regression introduced into Linux 4.11-rc.
Commit 816853f9dc4057b6c7ee3c45ca9bd5905 ("drm/amd/display: Set new

for the same format, which now matters for AMDGPU since we convert
implicit modifiers to explicit modifiers with multiple planes.
I checked other drivers and it doesn't look like they end up triggering

Currently, data for the device instance is held by vkms_device.
Add a separate type, vkms_config to contain configuration details

This config data stays constant once the device is created.
Accordingly, add vkms_create and
