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
