ASoC: dt-bindings: fsl,sai: Add AUDMIX mode support on i.MX952
The SAI can connect to AUDMIX, but AUDMIX can be bypassed or not on
i.MX952. There are three use cases:
1) SAI -> Codec (No AUDMIX between SAI and Codec)
2) SAI -> Codec (Has AUDMIX, but AUDMIX is bypassed)
3) SAI -> AUDMIX -> Codec (Has AUDMIX and used)
So add 'fsl,sai-amix-mode' property for this feature
fsl,sai-amix-mode = "none": is for case 1)
fsl,sai-amix-mode = "bypass": is for case 2)
fsl,sai-amix-mode = "audmix": is for case 3)
