ENGR00277299-1 dma: imx-sdma: Add other script for hdmi audio support

There's a missing script for hdmi audio support in current sdma driver,
thus add it.

This HDMI script doesn't use bd to copy memory like a normal one does
but only to update the memory address for HDMI internal AHB DMA and
then trigger its procedure automatically.
