Instead of calling gart memory on every bo pin,
allocates it on demand
v2: fix error handling
v3: drop the change for kfd gtt bo mapping, not needed.

Looks good to me on first glance, but I'm on vacation and can't do a full review right now.
One nit pick you could improve is to use "gart address space" instead of "gart memory" to avoid confusion.
Christian.
