Working AMD VEGA 56 based graphics card

[Johannes Lundberg]

Hi

This is exciting work! Please create issues on github for any bugs you
encounter.

https://github.com/FreeBSDDesktop/kms-drm/issues

amdgpu on recent hardware can be a bit flaky still. We hope to stabilize
this soon with the new 5.0 update and additional work on amdgpu
specifically.

Cheers
Johannes
