[PATCH 09/28] drm/amd/display: Fix 2nd DPIA encoder Assignment

[Stylon Wang]

From: Mustapha Ghaddar <mghaddar at amd.com>

[HOW & Why]
There seems to be an issue with 2nd DPIA acquiring link encoder for tiled displays.
Solution is to remove check for eng_id before we get first dynamic encoder for it
