spi: pl022: Only use DT-specified DMA channels
When a platform is booted with devicetree and does not provide a
platform data structure, the driver creates one internally. enable_dma
should not be set in this structure when creating it; the probe function
will set it later if DMA channels are specified via the devicetree.
Setting enable_dma = 1 when creating this internal platform data can
lead to pl022_dma_probe() finding bogus DMA channels (since there is no
channel filter specified) when no DMA channels are specified in the
devicetree.
