[PATCH 27/28] drm/amd/display: Assign preferred stream encoder instance to dpia

[Ray Wu]

From: Meenakshikumar Somasundaram <meenakshikumar.somasundaram at amd.com>

[Why]
For dpia, preferred engine instance availability is not checked
when assigning stream encoder instance.

[How]
Check for dpia preferred engine id and assign the same stream
encoder instance for the stream if available.
