dt-bindings: dma: ti: k3-udma: Update for atype support (virtualization)
In UDMA each channel can use different ATYPE value which tells UDMA how
the addresses in the descriptors should be treated:
0: pointers are physical addresses (no translation)
1: pointers are intermediate addresses (PVU)
2: pointers are virtual addresses (SMMU)
When virtualized environment is used then the dma binding should use
additional cell to configure the desired ATYPE for the channel.
