AMDGPU won't modeset at boot on RAVEN using agd5f's drm-next branch

The last thing I see before things appear to freeze is

fb0: switching to amdgpudrmfb from EFI VGA

Everything still continues to log

kernel.log

Looks like they key bit is:

TTM] [TTM] No compatible memory type found
amdgpu 0000:08:00.0: amdgpu: (-22) failed to allocate kernel bo
[drm:0xffffffff81d16190] *ERROR* sw_init of IP block <gmc_v9_0> failed -22

The current head is ff60ecff9a8b and the previous one which worked was either 58bf65ee142e or 14133a21f0b5
