drm/msm: get an iova from the address space instead of an id
In the future we won't have a fixed set of addresses spaces.
Instead of going through the effort of assigning a ID for each
address space just use the address space itself as a token for
getting / putting an iova.
This forces a few changes in the gem object however: instead
of using a simple index into a list of domains, we need to
maintain a list of them. Luckily the list will be pretty small;
even with dynamic address spaces we wouldn't ever see more than
two or three.
