spi: pl022: use DMA by default when probing from DT In the past we controlled the selection of DMA for a certain host by a boolean switch in the platform data. Currently there is no way to enable DMA on a PL022 probed from the device tree. Let's default to trying to obtain DMA channels in the DT case, and then we can always fail (and thus fall back to PIO mode).
