Add support for the external display module, which is a utility
to manage display interface and audio codec interactions
associated with the cable connect/disconnect events of the
display interfaces. The helper class is responsible for
routing operations called by the audio codec to a particular
display, and for creating and updating the audio switch nodes.
This implementation is based on a snapshot of the external
display module as of this commit 104eef6e1fe8d4d2 ("platform:
msm: Remove unused local count variable") on kernel-4.19.

The driver needs to ignore any Connector Change Events
before the Connector Change Indication notifications have
actually been enabled. This adds a check to
ucsi_connector_change() function to make sure the function
does not try to process the event unless the Connector
Change notifications have been enabled.
It is quite common that the firmware representing the "PPM"
(Platform Policy Manager) starts generating Connector Change
notifications even when only the Command Completion
notifications are enabled.

A possible deadlock could occur with the following flow:
arm_smmu_map_sg()
-->arm_smmu_secure_domain_lock()
-->ops->map_sg() //this returns an error with ret = 0
-->size_to_unmap = iova + size - __saved_iova_start;
-->goto out;
-->arm_smmu_assign_table()
-->arm_smmu_unmap()
---->arm_smmu_secure_domain_lock() //DEADLOCKed!!!!!
-------->mutex_lock()
The secure domain lock is needed to protect hyp assign and unassign.
Hence, its safe to call arm_smmu_secure_domain_unlock() after the
map and assign is done. Do this to avoid any runtime deadlocks.
