[ Upstream commit 025222a9d6d25eee2ad9a1bb5a8b29b34b5ba576 ]
This fixes a problem introduced while fixing ELD reporting with no jack set.
Most driver using the hdmi-codec will call the 'plugged_cb' callback directly when registered to report the initial state of the HDMI connector.
With the commit mentionned, this occurs before jack is ready and the initial report is lost for platforms actually providing a jack for HDMI.
Fix this by storing the hdmi connector status regardless of jack being set or not and report the last status when jack gets set.
With this, the initial state is reported correctly even if it is disconnected. This was not done initially and is also a fix.
