Subject: drm/amd/display: disable ext aux support for vega
Git-commit: 9c1a91f6f5db1482b989303c87e7b49f9bf844a7
Patch-mainline: v5.5-rc1
References: bsc#1152489

[Why]
Earlier changes to support configurable aux timeout
caused dc init failure on vega due to missing reg defs.
Needs to be disabled until implemented for vega.

[How]
Set extended aux timeout cap for vega to false.
