Some graphics APIs differentiate between out-of-graphics-memory and
out-of-host-memory (system memory). Add a device init flag to
have -ENOSPC propagated from the resource managers instead of being
converted to -ENOMEM, to aid driver stacks in determining what
error code to return or whether corrective action can be taken at
the driver level.
The first patch deals with a ttm_device_init() interface change,
The Second patch adds the actual functionality.
A follow-up will be posted for Xe once this is merged / backmerged.

drm/ttm: Change ttm_device_init to use a struct instead of multiple
bools
drm/ttm: Add a device flag to propagate -ENOSPC on OOM
