dv: display abnormal after hotplug hdmi [1/1]

PD#SWPL-13367

Problem:
HDMI hotplugged during video pause,
system control first set disable_video 1,
then DV core turn on due to sink changed,
then OMX sets disable video 2. DV core 1
is disabled after video_onoff_state is set to OFF.

Solution:
Monitor video status, parser and toggle once
to enable core1 when video off->on.

Verify:
SM1
