tegra: fb: Notify fbcon DC is unavailable
In the absence of hotplug, monitor data and mode database is removed
and DC is switched off. However, fbcon is unaware.
This patch adds the change to fb_info state to suspend while updating
monitor specs. This state will denote that the hardware is unavailable.
Info will be restored to state running once modelist is available.
