drm/msm/dpu: enable DPU_MDP_AUDIO_SELECT for sc8180x

According to the discussion ([1]) on the mailing list, platforms before
sm8250 (and derivatives) should program HDMI_DP_CORE_SELECT register to
route audio to the DP ports. Enable DPU_MDP_AUDIO_SELECT on sc8180x to
program correponding register.
