Another possibility is to list both:
<&apps_smmu 0x6c0 0x0>
<&apps_smmu 0x6c3 0x0>
which leaves 0x6c1 and 0x6c2 out of the picture, and makes 0x6c3

The SMMU that sits in front of the QUP needs to be programmed properly
so that the i2c geni driver can allocate DMA descriptors. Failure to do
this leads to faults when using devices such as an i2c touchscreen where
the transaction is larger than 32 bytes and we use a DMA buffer.
