spi: Add fsl-dspi driver
The fsl-dspi is found on Freescale Vybrid, Coldfire and Layerscape SoCs. This adds the driver based on the Linux driver as of v5.5. Coldfire support has been dropped as it's rather obsolete. Vybrid support has been dropped because it needs the DMA engine support we do not have in barebox. What's left is support for Layerscape where this driver has been tested on.
