msm: ext_display: update hpd and notify for HDMI
The semantic of hpd and notify have been changed. hpd is
a blocking call which notifies display and audio with the
cable status, and notify is used to complete the hpd call
which waits for the acknowledgment of power on/off. Update
these 2 interface implementations for HDMI.
