Ports the SOF DesignWare DMA code to Zephyr. Effectively replaces much of what was the designware driver as this driver enables scatter gather which the older driver did not. * Enables cyclic transfer description lists when the cyclic config param is given. * Enables linear link position usage with cAVS GPDMA. * Passes suspend/resume, scatter/gather tests. * Provides status updates of the transfer through dma_get_status() * Enables reloading a cyclic transfer with dma_reload() * Enables dma handshakes using the dma_slot config param. * cAVS specifics remain in the dma_cavs_gpdma driver.
