Sorry - that was totally unintentional, i was tinkering with spi and
got distracted on other part of this series (it's quite big for me,
first time tinkering with a series more than 5-6 patches).

The reason is that ep93xx DMA state is not quite device-tree ready at
this moment, and clients use it with the help of:

https://elixir.bootlin.com/linux/v6.4-rc4/source/include/linux/platform_data/dma-ep93xx.h

I was hoping to slip by without changing much in ep93xx DMA driver, so
i can deal with it later, especially seeing it's having some quirks
like:

https://elixir.bootlin.com/linux/v6.4-rc4/source/drivers/dma/ep93xx_dma.c#L471

And edb93xx and bk3 don't set use_dma with SPI for some reason.

I can move "use-dma" to module parameters, if this is acceptable.
