So add support hdmi in sdma driver. The design of hdmi script is different from common script such as sai. There is no need to config buffer descriptor for HDMI. The cyclic capability is achieved by the hdmi script. The slave config is so simple, only config src_addr, dts_addr and direction DMA_TRANS_NONE.
