Now that we are confident in providing full-ppgtt where supported, remove the ability to override the context isolation. v2: Remove faked aliasing-ppgtt for testing as it no longer is accepted. v3: s/USES/HAS/ to match usage and reject attempts to load the module on old GVT-g setups that do not provide support for full-ppgtt. v4: Insulate ABI ppGTT values from our internal enum (later plans involve moving ppGTT depth out of the enum, thus potentially breaking ABI unless we document the current values).
