Created attachment 64585 [details] [review] Adding an environment variable to disable VM if wanted

By setting R600_VM=0, we disable the virtual address space code path. By default, the path will still be enabled and used. However, if set to 0, it will prevent some cards (mostly CAYMAN it seems) from locking up or crashing because of the VM code. It is a work around until we figure out why it is locking.

Please, if someone could review and commit if possible.

Thank you. Alexandre Demers
