From: Andy Nguyen <theofficialflow1996@gmail.com>

[ Upstream commit 39f44f54afa58661ecae9c27e15f5dbce2372892 ]

The ASICREV_IS_BEIGE_GOBY_P check always took precedence, because it includes all chip revisions upto NV_UNKNOWN.

Fixes: 54b822b3eac3 ("drm/amd/display: Use dce_version instead of chip_id")
