drm/xe: Implement HW workaround 14016763929

Browse source

To workaround a HW bug on DG2, driver is required to map the whole
ppgtt virtual address space before GPU workload submission. Thus
set the XE_VM_FLAG_SCRATCH_PAGE flag during vm create so the whole
address space is mapped to point to scratch page.

v1:
  - Move the workaround implementation from xe_vm_create to
    xe_vm_create_ioctl - Brian
  - Reorder error checking in xe_vm_create_ioctl - Jose
  - Implement WA only for DG2-G10 and DG2-G12
