dma/cavs_hda: DMA driver for HDA on cAVS Adds an initial driver for HDA streams on cAVS. A common code base is provided for all HDA streams while the drivers are identified differently as they have small behavior differences. Uses dma_status to describe the positions for read/write. Uses dma_reload to inform when to move the read/write positions. This closely follows how HDA is being used in SoF Simple test case is provided for both drivers.

intel_adsp: Use device tree to enable/disable each HDA driver Uses the dt_compat_enabled Kconfig preprocessor to set defaults for each HDA driver. Each direction is uniquely selectable which can be useful when building with SOF where only some directions may wish to be enabled at any given time. By default, given the device tree (intel_cavs.dtsi) only the host directions are enabled but an overlay may adjust that as needed. Signed-off-by: Tom Burdick <thomas.burdick@intel.com>
