The SMARTDMA is a programmable DMA engine, and supports custom firmware
in order to run complex DMA operations. Update the driver to increase
the flexibility users have when configuring the SMARTDMA with
custom firmware, and remove the RT500 display firmware specific
definitions and functionality from the driver.
This display setup is now handled from the MIPI DSI driver, since the
firmware used for this case is specific to the MIPI DSI IP.
This change also requires an update to the RT500 devicetree, as the
register definition for the SMARTDMA has changed, so the base address
must as well.
