Add special function that executes a specially crafted circular DMA descriptor. The function doesn't wait for the descriptor to finish the transfer, since the descritor never finishes. This is useful when operating a SmartLCD through the LCDIF interface, as the LCDIF does not give us any means to have continuous refresh of the SmartLCD. Instead, the RUN bit in the LCDIF CTRL register must be triggered manually. This can be worked around by starting an DMA transfer which continuously sets the RUN bit. This function allows starting exactly such transfer.
