iommu/ipmmu-vmsa: Set the PTE contiguous hint bit when possible
iommu/ipmmu-vmsa: Set the PTE contiguous hint bit when possible

The contiguous hint bit signals to the IOMMU that a range of 16 PTEs
refer to physically contiguous memory. It improves performances by
dividing the number of TLB lookups by 16, effectively implementing 64kB
page sizes.
