When many devices share the same iova domain, iommu_dma_init_domain()
may be called at the same time. The checking of iovad->start_pfn will
all get false in iommu_dma_init_domain() and both enter init_iova_domain()
to do iovad initialization.
Fix this by protecting

Until now the port ID was always encoded as a 5-bit data. On MT8365,
the port ID is encoded as a 6-bit data. This requires to rework the
macros F_MMU_INT_ID_LARB_ID, and F_MMU_INT_ID_PORT_ID in order
to support 5-bit and 6-bit encoded port IDs.

The main purpose of this binding is to communicate Xen specific
information using generic IOMMU device tree bindings (which is
a good fit here) rather than introducing a custom property.
Introduce Xen specific IOMMU for the virtualized device (e.g. virtio)
to be used

Single memory zone feature will remove ZONE_DMA32 and ZONE_DMA. So add
the quirk IO_PGTABLE_QUIRK_ARM_MTK_TTBR_EXT to let level 1 and level 2
pgtable support at most 35bit PA.

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.
