iommu/vt-d: Preset Access bit for IOVA in FL non-leaf paging entries

iommu/vt-d: Preset Access bit for IOVA in FL non-leaf paging entries

The A/D bits are preseted for IOVA over first level(FL) usage for both
kernel DMA (i.e, domain typs is IOMMU_DOMAIN_DMA) and user space DMA
usage (i.e., domain type is IOMMU_DOMAIN_UNMANAGED).

Presetting A bit in FL requires to preset the bit in every related paging
entries, including the non-leaf ones. Otherwise, hardware may treat this
as an error. For example, in a case of ECAP_REG.SMPWC==0, DMA faults might
occur with below DMAR fault messages (wrapped for line length) dumped.

 DMAR: DRHD: handling fault status reg 2
 DMAR: [DMA Read NO_PASID] Request device [aa:00.0] fault addr 0x10c3a6000
    [fault reason 0x90]
    SM: A/D bit update needed in first-level entry when set up in no snoop
