Subject: drm/amdgpu: support B0&B1 external revision id for yellow carp
From: Aaron Liu <aaron.liu@xxxxxxx>
commit 53c2ff8bcb06acd07e24a62e7f5a0247bd7c6f67 upstream.
B0 internal rev_id is 0x01, B1 internal rev_id is 0x02.
The external rev_id for B0 and B1 is 0x20.
The original expression is not suitable for B1.
v2: squash in fix for display code (Alex)
