Ugh, OK, any ideas what sparc does to create these platform devices that
isn't of_platform_device_create_pdata() and has somehow grown an implicit
dependency on of_dma_configure() since 4.12? I'm looking, but nothing jumps
out...
I suspect it might be of_device_register(), called from
arch/sparc/kernel/of_device_64.c:scan_one_device()
arch/sparc/kernel/of_device_32.c:scan_one_device()
Right, that's as far as I got as well, so I'm struggling to see how
these things ever got DMA masks set before the of_dma_configure() call
moved out of of_platform_device_create_pdata(), or why it wasn't a
problem prior to the generic dma_ops rework if they didn't :/
