In the current implementation, there is a very small window for
the audio side to safely signal the hdmi_code_shutdown() before
the clocks are disabled.
Add some synchronization between the DP display and DP audio module
to safely disable the clocks to avoid unclocked access from audio
side.
In addition, audio side can open the sound card even if DP monitor
is not connected. Avoid programming hardware registers in this case
and bail out early.
Changes in v4:
- removed some leftover prints
Changes in v5:
- fix crash when user tries to play audio in suspended
state
Changes in v6:
- rebased on top of latest patchset of dependency

Add the hook_plugged_cb op for the MSM DP driver to signal connect
and disconnect events to the hdmi-codec driver which in-turn shall
notify the audio subsystem to start a new or teardown an existing
session.

Introduce audio support for Display Port on MSM chipsets.
This change integrates DP audio sub-module with the main
Display Port platform driver.
In addition, this change leverages hdmi_codec_ops to expose
the operations to the audio driver.
