drm/amdgpu: there is no vbios fb on devices with no display hw (v2)
If we enable virtual display functionality on parts with
no display hardware we can end up trying to check for and
reserve the vbios FB area on devices where it doesn't exist.
Check if display hardware is actually present on the hardware
before trying to reserve the memory.
v2: move the check into common code
