ENGR00224938 HDMI audio: clear HDMI dma done bit before start

HDMI hardware fix: signal of HDMI DMA DONE is hard connected to SDMA
event line. SDMA event is triggered by edge. If the HDMI DMA done is
already 1 before start, there would be no SDMA event being trigged after
HDMI generates another HDMI DONE signal.

In this patch, clear HDMI DONE bit before start HDMI audio DMA.
