The PCI on Juno is DMA coherent, which means it should not be

This is wrong. The module .inf lists library *classes* and the
platform .dsc decides how each class maps onto an implementation (aka
library resolution)
Agree. However, this is platform specific module and as i understand,
the behavior of it will not change so, I think, having NullDmaLib here
will be appropriate as well. We can move it to .dsc file, if it fits
better to the platform description/module dependencies structure.
IOW, the other patch you sent that updates ARM Juno's .dsc is sufficient.
