    drm/i915: Disable read only ppgtt support for gen11

    On gen11 writing to read only ppgtt page causes a gpu hang.
    This behaviour is different than with previous gen where
    read only ppgtt access is supported. On those, the write
    is just dropped without visible side effects.

    Disable ro ppgtt support on gen11 until a solution can
    be found to bring it into line with its predecessors.
