This patch introduces a new function intel_vgpu_reset_gtt() to reset the all GTT related status, including GGTT, PPGTT, scratch page. This function can free all shadowed PPGTT, clear all GGTT entry, and clear scratch page to all zero. After this, we can ensure no gtt related information can be leakaged from one VM to anothor one when assign vgpu instance across different VMs (not simultaneously).
