iommu/vt-d: Fix pointer cast warnings on 32 bit
Pointers should be casted to unsigned long to avoid "cast from pointer
to integer of different size" warnings.
drivers/iommu/intel-pasid.c:818:6: warning:
cast from pointer to integer of different size [-Wpointer-to-int-cast]
drivers/iommu/intel-pasid.c:821:9: warning:
cast from pointer to integer of different size [-Wpointer-to-int-cast]
drivers/iommu/intel-pasid.c:824:23: warning:
cast from pointer to integer of different size [-Wpointer-to-int-cast]
drivers/iommu/intel-svm.c:343:45: warning:
cast to pointer from integer of different size [-Wint-to-pointer-cast]
Fixes: b0d1f8741b81 ("iommu/vt-d: Add nested translation helper function")
Fixes: 56722a4398a3 ("iommu/vt-d: Add bind guest PASID support")
