Works completely fine on both Ultra 1 and Ultra 2 - nothing DMA-relaated
in dmesg.
Updated version including that has survived contact with a sparc cross
compiler below. Note that this is on top of the previous patch adding
a dma_mask to struct platform_device, which I've included as well.

This should have been around since the warning was added.
The patch below should fix it:
Tried yesterdays git 4.18.0-12789-gaa5b105 on a Sun Ultra 1 with SBus
and several SBus connected devicess give DMA mapping related warnings:
