Patch to mitigate HDMI Suspend/Resume crash/noise during Audio Playback.

Patch to mitigate HDMI Suspend/Resume crash/noise during Audio Playback.

We were sending HAD DRM_DPMS_ON event when resuming from sleep state
in gfx_late_resume. Which was causing the HAD HOT_PLUG sequence to
run again causing:
 1. Audio Noise
 2. Random crash.

With this patch, we handle the situation by checking if audio stream
is busy in resume sequence. If yes, we don't send DRM_DPMS_ON in
gfx_late_resume to both Local MIPI and HDMI as we never send
DRM_DPMS_OFF in case HDMI audio is busy becasue of a known JIRA
issue - ANDROID-1553. Otherwise we turn them ON.
After the Jira issue is resolved, we can turn the local MIPI
sequence independent of HDMI Audio state.

Refer JIRA: ANDROID-1553 for more details.
