    drm/i915: Remove i915.enable_ppgtt override

    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).
