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.
