iommu/io-pgtable-arm-v7s: Add a quirk to allow pgtable PA up to 35bit
[ Upstream commit bfdd231374181254742c5e2faef0bef2d30c0ee4 ]
Single memory zone feature will remove ZONE_DMA32 and ZONE_DMA and
cause pgtable PA size larger than 32bit.
Since Mediatek IOMMU hardware support at most 35bit PA in pgtable,
so add a quirk to allow the PA of pgtables support up to bit35.
