ALSA: hda/hdmi: Don't skip notification handling during PM operation 

The HDMI driver skips the notification handling from the graphics
driver when the codec driver is being in the PM operation.  This
behavior was introduced by the commit eb399d3c99 ("ALSA: hda - Skip
ELD notification during PM process").  This skip may cause a problem,
as we may miss the ELD update when the connection/disconnection
happens right at the runtime-PM operation of the audio codec.

Although this workaround was valid at that time, it's no longer true;
the fix was required just because the ELD update procedure needed to
wake up the audio codec, which had lead to a runtime-resume during a
runtime-suspend.  Meanwhile, the ELD update procedure doesn't need a
codec wake up any longer since the commit 788d441a16 ("ALSA: hda -
Use component ops for i915 HDMI/DP audio jack handling"); i.e. there
is no much reason for skipping the notification.

Let's drop those checks for addressing the missing notification.
