MLK-20095-2: arm64: dts: Make pd_asrc0 dependent on pd_esai0 

Because now DSP supports ASRC we need to power up pd_asrc0
each time pd_esai0 is powered up.

Current power domain tree looks like this:

	* pd_audio
	  * pd_audio_clk0
	    * pd_audio_clk1
	      * pd_dma0_chan6
	        * pd_dma0_chan7
	          * pd_esai0
	      * pd_dma0_chan0
	        * pd_dma0_chan1
	          [....]
	         * pd_asrc0

We need to make pd_asrc0 dependent on pd_esai0, thus we move
pd_dm0_chan6 node as a child of pd_asrc0.

Thus, the new power domain hierarch will look like this:

	* pd_audio
	  * pd_audio_clk0
	    * pd_audio_clk1
	      * pd_dma0_chan0
	        * pd_dma0_chan1
	          [....]
	         * pd_asrc0
	           * pd_dma0_chan6
	             * pd_dma0_chan7
	              * pd_esai0
