[PATCH v2] drm/msm: populate intf_audio_select() base on hardware capability

[Kuogee Hsieh]

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
