During dp altmode driver initialization, the dp altmode driver is called
with a null data packet. Even though this callback indicates a disconnect,
the multi function flag is incorrectly set to true. If the DP is enabled
later using simulation mode, the multi function flag is not cleared thereby
limiting the lane count to 2 irrespective of capability applied through
DPCD.
This change checks for the zero pin value while setting the multi function
flag.

When a physical DP sink is connected after a simulation
session, the attention events from the sink are ignored.
The forced_disconnect flag prevents handling of attention
events when disconnect is simulated or forced. This flag
does not get reset when a physical sink is connected.
Certain sinks which lose link integrity after link
training sequence fail to display image.
This change will reset the flag so that the attention
events which occur after the cable hotplug can be processed.

Deregister the altmode notifier in the client teardown path since
the client will no longer be available to handle altmode
registration.

and attention events.
