spi/pxa2xx: add support for DMA engine To be able to use DMA with this driver on non-PXA platforms we implement support for the generic DMA engine API. This lets user to use different DMA engines with little or no modification to the driver. Request lines and channel numbers can be passed to the driver from the platform specific data. The DMA engine implementation will be selected by default even on PXA platform. User can select the legacy DMA API by enabling Kconfig option CONFIG_SPI_PXA2XX_PXADMA.
