MSM8939 does not have a dedicated ADSP. Instead, the audio services via APR are also implemented by the modem DSP. Audio can be either routed via the modem DSP (necessary for voice call audio etc) or directly sent to the LPASS hardware (currently used by DB410c). Bypassing QDSP6 audio is only possible with special firmware (on DB410c) or when the modem DSP is completely disabled. Add the typical nodes for QDSP6 audio to msm8939.dtsi. The apr node is disabled by default to avoid changing behavior for devices like apq8039-t2 that use the bypassed audio path.
