intf_audio_select() callback function use to configure HDMI_DP_CORE_SELECT to decide audio output routes to HDMI or DP interface. HDMI is obsoleted at newer chipset. To keep supporting legacy hdmi application, intf_audio_select call back function have to be populated base on hardware chip capability where legacy chipsets have has_audio_select flag set to true.
Changes in V2: -- remove has_audio_select flag -- add BIT(DPU_MDP_AUDIO_SELECT) into dpu_mdp_cfg
